Zend Framework Step By Step Tutorial - Part 1: Zend framework is one of popular framework at PHP World. This framework is released by Zend, a big vendor for PHP. In this post, We learn Zend framework from zero. We will build a simple application named "helloworld". In this framework, we use MVC (Model View Controller). We ever talk about this pattern at Joomla MVC. Our target is create simple application like this:
First, create folder structure like this at your web server folder (I create under www/test/zend. Up to you. You can create under www/test or just www).
Then, download zend framework from here. Extract compressed file. You may get structure like this:
Copy zend library (folder named "zend" under library) to helloworld/library. Thus, your application become like this:
Next post, I will explain meaning of the folders.
Zend Framework Intro: Explaining Anatomy of Zend Framework Application
Tag: framework, zend, zend framework, anatomy application, MVC Category: PHP Framework post: 08 Apr 2008 read: 1,960 Zend Framework Step By Step Tutorial ‐ Part 2: We have created folder structure for helloword applicaton use zend framework. What we created is standard for Model View Controller pattern at zend framework application. In this post, we will see what function each folders.
There are 4 top level directories within application's folder: 1. Application 2. library 3. test 4. web_root
The Application Folder
The application folder contains all the code required to run the application. User can not accessed directly. This is separation between display, business, and control logic modele. Under this application, there are models, views, and controllers folder. These folders contain the model, view, and controller files. Other folders still may be created, for example for configuration files.
The Library Folder
All applications use zend library. We place zend framework here. but, substantively, we can store library at anywhere. But make sure the application can find them. You can store at a global include directory that accessible for php application on the server, such as /usr/php_include or c:\code\php_include. Make sure set php.ini configuration file (or you can use set_include_path() function).
The Test folder
This folder is used to store all unit tests that are written. If you still don't know about unit test, you can read at this. many PHP programmers do not place unit test as special step. How about you?
The web_root folder
All web request from user are channeled through a single file, usually called index.php. This file is the only php file that needs to be accessible by web server. This file is placed in the web_root. Other common files that can be accessed directly are images, css, and JavaScript files. Each of them has own sub-directory within web_root directory. Next, we will write code for simple application named helloworld.
Zend Framework Intro: Creating Index.php as Single Access File
Tag: framework, zend, zend framework, access file, controller, MVC Category: PHP Framework post: 08 Apr 2008 read: 1,845
Zend Framework Step By Step Tutorial - Part 3: As we know, at Zend Framework, index.php is a file that needed in the web root directory. This file is used for all page request. It is used for setting up the application's environtment, Zend framework's controller system, then running the application itself. This is Front Controller pattern. Create a file named "index.php" within helloworld/web_root. Enter following code: 1 view plain | print Ok, let's look at this file in more detail. Line 2-4 is used for setup environtment. Line 3 to ensure that all errors or notices are displayed. Line 4 for setup default time zone. include_path() specifies a list of directories where the require(), include() and fopen_with_path() functions look for files. You can set at php.ini. But, we don't have to do it. We can use set_include_path(). You can see at line 7. This is the bootstrap file. Bootstrapping is the term used to describe starting the application up. The core of this code at line 9-10. This will instantiate and dispatch the front controller. It will route request to action controllers.
Zend Framework Intro: Creating Apache .htaccess
Tag: framework, zend, zend framework, htaccess, mod_rewrite, apache Category: PHP Framework post: 08 Apr 2008 read: 1,778
Zend Framework Step By Step Tutorial - Part 4: We need route any requests to the front controller. We can use module from apache named "mod_rewrite". About this module, you can read at this post. Then, we will work with .htaccess file. This file will do routing job. Create a file named ".htaccess" within web_root. Then enter following code: 1RewriteEngine On 2RewriteRule .* index.php view plain | print At the line 2, we can see, Apache will route all request to index.php. Simple code, isn't it?
Another option, you can configure it directly in Apache's httpd.conf file. We know, it is not easy way if we don't have own server. Thus, configure in a local Apache configuration file named .htaccess is better option.
Zend Framework Intro: Creating Controller
Tag: framework, zend, zend framework, controller, MVC Category: PHP Framework post: 09 Apr 2008 read: 1,976
Zend Framework Step By Step Tutorial - Part 5: The front controller pattern maps the URL requested by the user to a particular member function within a specific controller class. We called as routing and dispatching. The controller class have a strict naming convention requirement. The router calls a function named {actionname}Action() within the {ControllerName}Controller class. This class must be within a file called {ControllerName}.php. If not provide, index will be used. Still confuse? look at this example: Create a file named "IndexController.php" within application/controllers. Enter following code: 1 view->assign('title', 'Hello, World!'); 9 } 10 11} 12?> view plain | print Within the front controller system, the dispatcher expects to find a file called IndexController.php within the application/controllers directory. This file must contain a class called Indexcontroller and, as a minimum, contain a function called indexAction().
Zend Framework Intro: Creating View
Tag: framework, zend, zend framework, access file, view, MVC Category: PHP Framework post: 09 Apr 2008 read: 1,787
Zend Framework Step By Step Tutorial - Part 6: Now, we need to provide a view template for displaying. We will create a index.phtml file. This file is stored within the views/scripts/index. We have a separate directory for each controllers view templates. Create a file named "index.phtml" within views/scripts/index. Enter following code: 1 2 3 4
5
<? echo $this->escape($this->title); ?> 6 7 8 9
escape($this->title); ?>
10 11 view plain | print The template file is executed within a member function of Zend_View and so $this is available within the template file wich is the gateway to Zend_View's functionality. All variables that have been assigned to the view from within the controller are availabel directly as properties of $this. You can see sample at above, $this->title.

Zend Framework Action Step By Step Tutorial - Part 1: Previous post, we ever talk little about assign parameter to view. This value is sent from controller. This can happen because Action Controller. I will not talk much detail about Action Controller, but, we will learn implementation of Action Controller in web development. First, just remembering about passing value from controller to view. We wrote code like this: 1 view->assign('title', 'Hello, World!'); 9 } 10 11}
12?> view plain | print View will catch with like this: 1escape($this->title); ?> view plain | print If you still don't know what we talk about, please read this series about Zend Framework Introduction. Ok, now, add one or more parameter such as: 1 2 3 4 5 6 7 8 view->assign('title', 'Hello, World!'); $this->view9 >assign('wellcome','Wellcome to my site. This site is built using Zend Framework. Enjoy it!'); 10 $this->view->assign('webmaster','Wiwit'); 11 } 12 13} 14?> view plain | print Then, change you "index.phtml" within application/views/scripts/index. 2 3 4

Zend Framework Action: URL Structure and Controller
Tag: framework, zend, zend framework, actions, url structure, controller Category: PHP Framework post: 11 Apr 2008 read: 1,215
Zend Framework Action Step By Step Tutorial - Part 2: URL is important part when we develop web application. We use them for jump between pages. As we know, every framework have rule about URL. It is a key to understanding how the framework works. Now, we will talk rule at Zend Framework. Zend Framework breaks URL into pieces. Those pieces are laid out as follows: http://hostname/controller/action/parametes. Look at our url that we used to access hello page: http://localhost/test/zend/helloworld/web_root/. Assume http://hostname is same with http://localhost/test/zend/helloworld/web_root/. Next path is controller. Try to point your browser to http://localhost/test/zend/helloworld/web_root/index. We get same with http://localhost/test/zend/helloworld/web_root/. Why? as default, http://localhost/test/zend/helloworld/web_root/ will access index controller. Can you catch idea? I know, you don't patient to test with other controller. How about we use other controller named "user"? Never mind. From theory above, we will access with http://localhost/test/zend/helloworld/web_root/user. Let's do it. First, create controller name "UserController". Create a file named "UserController" within application/controllers. Enter following code: 1 view->assign('name', 'Wiwit'); 9 $this->view->assign('title', 'Hello'); 10 } 11 12} 13?> view plain | print
Next, create a folder named "user" within helloworld\application\views\scripts. Create a file named "index.phtml" within user. Enter following code: 2 3 4
5
<? echo $this->escape($this->title); ?> 6 7 8 9
escape($this->title);?>, escape($this->name);?>
10 11 view plain | print Now, point your browser to http://localhost/test/zend/helloworld/web_root/user.
Zend Framework Action: URL Structure and Action
Tag: framework, zend, zend framework, actions, url structure, controller Category: PHP Framework post: 11 Apr 2008 read: 1,186
Zend Framework Action Step By Step Tutorial - Part 3: Just remember, we have rule like this: http://hostname/controller/action/parametes. We have talked about controller. Now, we discuss next part, action. For simply, action is method in our class at controller. Look at our code: 1 view->assign('name', 'Wiwit'); 9 $this->view->assign('title', 'Hello'); 10 } 11 12} 13?> view plain | print Above, we have action name "index". Naming in Zend Framework, add with Action. Thus, we have action "indexAction". When we call this controller (such as user), but we don't specify action, it will call indexAction as default.
Now, add a method in there, example "nameAction" such as: 1public function nameAction() 2{ 3 $this->view->assign('name', 'Wiwit'); 4 $this->view->assign('title', 'User Name'); 5} view plain | print Below, complete our userController: 1 view->assign('name', 'Wiwit'); 9 $this->view->assign('title', 'Hello'); 10 } 11 12 public function nameAction() 13 { 14 $this->view->assign('name', 'Wiwit'); 15 $this->view->assign('title', 'User Name'); 16 } 17 18} 19?> view plain | print Next, create a file named "name.phtml" within views/scrips/user. Enter following code:
<? echo $this->escape($this->title); ?>
1
2 3 4 5 6 7 8 9
escape($this->title);?>, escape($this->name);?>
10 11 view plain | print
Now, point your browser to http://localhost/test/zend/helloworld/web_root/user/name

Zend Framework Action Step By Step Tutorial - Part 4: Now, we talk last part or URL in Zend Framework, parameters. Ok, what the rule in Zend Framework? Look this URL sample: 1http://hostname/user/name/username/wiwit/gender/man view plain | print We can interpret like this: 1. 2. 3. 4. Controller = user Action = name username = wiwit gender = man
What is your conclusion? Yeah, we have general formula like this: 1http://hostname/controller/action/var1/value1/var2/value2/... view plain | print How to catch the parameters? Ok, we can learn from sample. Open UserController.php within application/controller. Update became like this: 1 view->assign('name', 'Wiwit'); 9 $this->view->assign('title', 'Hello'); 10 } 11 12 public function nameAction() 13 { 14 15 $request = $this->getRequest(); 16 $this->view->assign('name', $request->getParam('username')); 17 $this->view->assign('gender', $request->getParam('gender')); 18 19 $this->view->assign('title', 'User Name'); 20 } 21} 22?> view plain | print
Give attention at line 15-17. It is clear, isn't it? Last, update your view: "name.phtml":
<? echo $this->escape($this->title); ?>
1
2 3 4 5 6 7 8 9
escape($this->title);?>, escape($this->name);?>

Zend Framework Database: Intro
Tag: framework, zend, zend framework, database Category: PHP Framework post: 12 Apr 2008 read: 2,563
Zend Framework Database Step By Step Tutorial - Part 1: Zend Framework provides classes for supporting database. Name of that class is Zend_Db. More benefit using this class and its related classes is features that offer simple SQL database interface. If we talk about database in Zend Framework, we may talk what is Zend_Db_Adapter. This is basic class you use to connect your PHP application to and RDBMS. As we know, there is a different adapter class for each brand of RDBMS. The Zend_Db_Adapters is a bridge from the vendor-specific PHP extensions to a common interface. With this class, you can write PHP application for multi brands of RDBMS (with little effort). May be you remember there is extension at PHP that have function like Zend_Db_Adapter, PHP Data Object (PDO). PDO provide interface for multi database at PHP 5. At PHP 4, we know a library, ADOdb. About PHP ADOdb, you can read this post. in this practice, we will use PDO for mysql (pdo_mysql). First try to check availabelity pdo_mysql in your system. Check in your php.ini. uncomment extension=php_pdo.dll,extension=php_pdo_mysql.dll, then restart your apache. Ok, just remmembering, this practise base on our previous practice at here and here. So, make sure that you have followed that practice.
For this practice, create a database named "zend". Then create a table named "user". You can use this query: 1CREATE TABLE `user` ( 2 `id` int(11) NOT NULL auto_increment, 3 `first_name` varchar(50) NOT NULL, 4 `last_name` varchar(50) NOT NULL, 5 `user_name` varchar(50) NOT NULL, 6 `password` varchar(255) NOT NULL, 7 PRIMARY KEY (`id`), 8 UNIQUE KEY `user_name` (`user_name`) 9); view plain | print
Zend Framework Database: Creating Input Form
Tag: framework, zend, zend framework, database, form Category: PHP Framework post: 12 Apr 2008 read: 2,432
Zend Framework Database Step By Step Tutorial - Part 2: First step, we will create a form for inputing data. We create this form at User Controller. We just add method named "registerAction" as action for this controller. Open "UserController.php" within application/controllers. Add following method: 1 public function registerAction() 2 { 3 $request = $this->getRequest(); 4 5 $this->view->assign('action',"process"); 6 $this->view->assign('title','Member Registration'); 7 $this->view->assign('label_fname','First Name'); 8 $this->view->assign('label_lname','Last Name'); 9 $this->view->assign('label_uname','User Name'); 10$this->view->assign('label_pass','Password'); 11$this->view->assign('label_submit','Register'); 12$this->view->assign('description','Please enter this form completely:'); 13 } view plain | print As we know, if we create action name "registerAction", we must create a view named "register.phtml". Ok, create a file named "register.phtml" within application/views/scripts/user. Enter following code: 1 2

Zend Framework Registry: Setting and Reading Values
Tag: framework, zend, zend framework, registry, zend_registry Category: PHP Framework post: 16 Apr 2008 read: 1,041
Zend Framework Registry Step By Step Tutorial - Part 1: What is registry? It is like global storage. We just register values then we can use throughout application. For example, we can store name of application, thus every time we need to display name of application, we just call from registry. To use registry, we call registry.php from Zend Framework: 1require_once 'Zend/Registry.php'; view plain | print Ok, we practice using registry. We still use our previous practice. Please read that tutorial before. Then, follow this steps: 1. Open "index.php" within "web_root". Enter line 11 - 13: 1 view plain | print 21. We set a parameter named "title". We put a value for this parameter. 22. Next, we try to call/read this registry. Open your UserController.php within application/controllers. 23. Update indexAction like this: 1public function indexAction() 2{ 3 $title = Zend_Registry::get('title'); 4 $this->view->assign('name', 'Wiwit'); 5 $this->view->assign('title', $title); 6} view plain | print Test, by pointing your browser to : http://localhost/test/zend/helloworld/web_root/user/.
You may remember a function at PHP that have function like this, define(). Yup, it is like register global parameter.

Ok, follow this steps to understand. Open again your "index.php" within web_root. Update become like this: 1 view plain | print We register a array parameter named "credits" at line 15-16. How to read it? Ok, we test by update again "UserController.php". Update at indexAction become: 1 2 3 4 5 6 public function indexAction() { $registry = Zend_Registry::getInstance(); $title = $registry['title']; $credits = $registry['credits'];

It can we use to read several values from registry. Ok, before test it. Please update view at index.phtml within application/views/scripts/user. Update with following code: 2 3 4
5
<? echo $this->escape($this->title); ?> 6 7 8 9
escape($this->title);?>, escape($this->name);?>

Zend Framework Configuration Step By Step Tutorial - Part 1: There are important information where we build a database application such as host of database, database name, user, database, name of application, and so on. These informations are retrieved extensively. It will concise if we put them on a configuration part. Zend Framework have zend_config, is designed to simplify access to and use of configuration data within applications. In this post, we see how to implement zend_config use array. For case, see our code from previous tutorial: 1 'localhost', 20 'username' =>'root', 21 'password' =>'admin', 22 'dbname' =>'zend' 23 ); 24$DB = new Zend_Db_Adapter_Pdo_Mysql($params); 25 26$DB->setFetchMode(Zend_Db::FETCH_OBJ); 27Zend_Registry::set('DB',$DB); 28 29 30 31Zend_Controller_Front::run('../application/controllers'); 32 33?> view plain | print
That is index.php. Location code above at web_root. Line 14 and 19-23 often use along application.

In this tutorial series, we will talk how to create simple login system at Zend Framework. There are several possible scenario, but I will choose login with database. It means, we need database for store member data. We still use same database from previous practice. The database name is "zend". Now, create table for store members information. The table name is "users". You can use this query: 1CREATE TABLE `users` ( 2 `id` int(11) NOT NULL auto_increment, 3 `username` varchar(50) NOT NULL, 4 `password` varchar(255) NOT NULL, 5 `real_name` varchar(50) NOT NULL, 6 PRIMARY KEY (`id`), 7 UNIQUE KEY `username` (`username`) 8); view plain | print Now, try to insert sample member data for example: 1INSERT INTO `users` 2(`id`, `username`, `password`, `real_name`) 3VALUES 4(1, 'admin', '21232f297a57a5a743894a0e4a801fc3', 'Administrator'); view plain | print Above, we insert a member with user name "admin".

Zend Framework Login System Step by Step Tutorial - Part 4: We run previous post, I get error message like this: Fatal error: Cannot use object of type stdClass as array in
C:\AppServ5\www\test\zend\helloworld\ library\Zend\Auth\Adapter\DbTable.php on line 340. If you are same like me, let's fix this problem. Skip this post if you don't fine any error at previous post. Sadly, I still didn't have much time to know about this error when I was writing this post. So, I decide to fix at core of Zend library. I will tell you latter if I find fixing this error more better than this post. Ok, open DbTable.php within library\Zend\Auth\Adapter\. Update line 340: Before: 1if ($resultIdentity['zend_auth_credential_match'] != '1') { view plain | print Become: 1if ($resultIdentity->zend_auth_credential_match != '1') { view plain | print Then, update line 346: 1unset($resultIdentity['zend_auth_credential_match']); view plain | print Become: 1unset($resultIdentity->zend_auth_credential_match); view plain | print I will update this post if there is more better than this way.

Zend Framework Login System Step by Step Tutorial - Part 5: We have created authentication at previous post. Now, we try to protect a page. Thus, when not member try to enter the page, they will be redirected to login form. First, create view. Create a file named "userpage.phtml" within application/views/scripts/user. Enter following code: 1 2Hello, escape($this->username);?>
3Logout 4 view plain | print Then, we add method at controller. Open "UserController.php". Add following method:

Zend Framework Login System Step by Step Tutorial - Part 6: At protected page (in previous post), we had created a link to logout. This post talk about logout page. First, create view for logout. Create a file named "logout.phtml" within application/views/scripts/user. Leave blank (because we don't want to show anything). Then, we create a method for controller named logoutAction(). Open "UserController.php" within application/controllers. Add following method: 1public function logoutAction() 2{ 3 $auth = Zend_Auth::getInstance(); 4$auth->clearIdentity(); 5$this->_redirect('/user'); 6} view plain | print We just use clearIdentity(). Then redirect page to another page (in this sample to user).

Zend Framework Session: Introduction
Tag: framework, zend, zend framework, session Category: PHP Framework post: 23 Apr 2008 read: 1,621
Zend Framework Session Step By Step Tutorial - Part 1: Session is a familiar word in PHP programming. When we build complex application, usually, we involved session. In PHP, we know $_SESSION. It represent a logical, one to one connection between server-site, persistent state data, and user agent client (e.g, web browser).
At Zend Framework, we can use Zend_Session. Zend_Session manage server-side data stored in $_SESSION. And a important class that we must know is Zend_Session_Namespace. Session namespaces provide access to session data using classic namespaces implemented logically as named groups of associative arrays, keyed by strings (similar to normal PHP arrays). Below, is quotes from zend framework manual: Zend_Session_Namespace instances are accessor objects for namespaced slices of $_SESSION. The Zend_Session component wraps the existing PHP ext/session with an administration and management interface, as well as providing an API for Zend_Session_Namespace to persist session namespaces. Zend_Session_Namespace provides a standardized, object-oriented interface for working with namespaces persisted inside PHP's standard session mechanism. Support exists for both anonymous and authenticated (e.g., "login") session namespaces. Zend_Auth, the authentication component of the Zend Framework, uses Zend_Session_Namespace to store some information associated with authenticated users. Since Zend_Session uses the normal PHP ext/session functions internally, all the familiar configuration options and settings apply (see http://www.php.net/session), with such bonuses as the convenience of an objectoriented interface and default behavior that provides both best practices and smooth integration with the Zend Framework. Thus, a standard PHP session identifier, whether conveyed by cookie or within URLs, maintains the association between a client and session state data. Still confuse? Don't worry, next post we will try to practice about session at Zend Framework. We will begin with Zend_Session_namespace.
Zend Framework Session: Using Namespace
Tag: framework, zend, zend framework, session, namespace Category: PHP Framework post: 23 Apr 2008 read: 2,005
Zend Framework Session Step By Step Tutorial - Part 2: In this post, we will learn to implement namespace into session at Zend Framework. If you are not familiar with namespace, don't worry. It is simple. Let's do it. Simply, namespace is like name of groups of associative arrays, keyed by strings. For practice, we use our previous practice. Ok, we want to count number of a particular page request form a visitor. See this picture:
To do this, open your UserController.php within application/controllers. Include Zend/Session/Namespace.php at first line after delimeter. 1require_once 'Zend/Session/Namespace.php'; view plain | print Edit loginFormAction() method become like this: 1 public function loginFormAction() 2 { 3 $request = $this->getRequest(); 4 5 $ns = new Zend_Session_Namespace('HelloWorld'); 6 7 if(!isset($ns->yourLoginRequest)){ 8 $ns->yourLoginRequest = 1; 9 }else{ 10 $ns->yourLoginRequest++; 11} 12 13$this->view->assign('request', $ns->yourLoginRequest); 14$this->view->assign('action', $request->getBaseURL()."/user/auth"); 15 $this->view->assign('title', 'Login Form'); 16 $this->view->assign('username', 'User Name'); 17 $this->view->assign('password', 'Password'); 18 19 } view plain | print At line 5, we define object of namespace. The namespace, we named "HelloWorld". It is like $_SESSION['HelloWorld']. You can put name such as mynamespace, myapplication, etc. Next, at line 7, we check value of $ns->yourLoginRequest. It is like $_SESSION['HelloWorld']['yourLoginRequest']. Next, modify loginform.phtml within application/views/scripts/user. Update become like this: 1 2 escape($this->title);?>
3 You have entered this page: escape($this->request);?> time(s). 4 17 view plain | print Now, point your browser to http://localhost/test/zend/helloworld/web_root/user/loginform. You may get screen like picture above. Ok, try again for userPageAction() at controller. Update become like this: 1 public function loginFormAction() 2 { 3 $request = $this->getRequest(); 4 5 $ns = new Zend_Session_Namespace('HelloWorld'); 6 7 if(!isset($ns->yourLoginRequest)){ 8 $ns->yourLoginRequest = 1; 9 }else{ 10 $ns->yourLoginRequest++; 11} 12 13$this->view->assign('request', $ns->yourLoginRequest); 14$this->view->assign('action', $request->getBaseURL()."/user/auth"); 15 $this->view->assign('title', 'Login Form'); 16 $this->view->assign('username', 'User Name'); 17 $this->view->assign('password', 'Password'); 18 19 } view plain | print Then, update its view at application/views/scripts/user/userpage.phtml: 1 2Hello, escape($this->real_name);?>

Zend Framework Session Step By Step Tutorial - Part 3: In this post, we learn how to access session data. Now, we talk about how to access the session.
Please, give attention a code at previous post: 1$ns = new Zend_Session_Namespace('HelloWorld'); 2 3if(!isset($ns->yourLoginRequest)){ 4 $ns->yourLoginRequest = 1; 5}else{ 6 $ns->yourLoginRequest++; 7} view plain | print From above, we know how to set session at Zend framework. Just give properties such as: 1$ns->yourLoginRequest = 1; 2$ns->thisIsSession = "Oke"; 3$ns->nameOfSession = "MySession"; 4$ns->foo = 10; view plain | print Now, how to access the values? Just simple: 1echo $ns->yourLoginRequest; 2echo $ns->thisIsSession; 3echo $ns->nameOfSession; 4echo $ns->foo; view plain | print
Zend Framework Session: Seing All Values at Namespace
Tag: Category: PHP Framework post: 23 Apr 2008 read: 814
Zend Framework Session Step By Step Tutorial - Part 4: This is a little tips to show all value at a namespace. As we know, session can have behavior like array. So, we can show values like array. Look this sample: 1$ns = new Zend_Session_Namespace('HelloWorld'); 2foreach ($ns as $index => $value) { 3 echo "ns->$index = '$value';"; 4} view plain | print Ok, try to test it. We have put session at loginform and userpage page. Now, we want to show request statistic for that page. Open your "UserController.php" within application/controllers. Add following method: 1public function statsAction() 2{ 3 $ns = new Zend_Session_Namespace('HelloWorld');
4 foreach ($ns as $index => $value) { 5 echo "ns->$index = '$value';"; 6 echo "
"; 7 } 8 9} view plain | print Then, create a view for this action controller. Create a file named "stats.phtml" within application/views/scripts/user. Leave blank. Ok, try to point your browser to http://localhost/test/zend/helloworld/web_root/user/stats. You may get such as: 1ns->yourLoginRequest = '2'; 2ns->yourUserPageRequest = '7'; view plain | print Values depend on number of visiting.
Zend Framework Session: Locking and Unlocking Namespace
Tag: framework, zend, zend framework, session, namespace Category: PHP Framework post: 23 Apr 2008 read: 1,029
Zend Framework Session Step By Step Tutorial - Part 5: Session namespaces can be locked. What's that mean? When a namespace session is locked, we can not update or delete value of session. it will be readonly. We can use lock() to lock namespace. Then, if want to check whether locked or not, use isLocked(). Look this sample: 1 public function loginFormAction() 2 { 3 4 $ns = new Zend_Session_Namespace('HelloWorld'); 5 $ns->lock(); 6 7 if (!$ns->isLocked()) { 8 if(!isset($ns->yourLoginRequest)){ 9 $ns->yourLoginRequest = 1; 10 }else{ 11 $ns->yourLoginRequest++; 12 } 13 } 14 15 $request = $this->getRequest(); 16$this->view->assign('request', $ns->yourLoginRequest); 17$this->view->assign('action', $request->getBaseURL()."/user/auth");
18 $this->view->assign('title', 'Login Form'); 19 $this->view->assign('username', 'User Name'); 20 $this->view->assign('password', 'Password'); 21 22 } view plain | print To unlock, you can use unLock() method. 1$ns= new Zend_Session_Namespace('HelloWorld'); 2 3// marking session as read only locked 4$ns->lock(); 5 6// unlocking read-only lock 7if ($ns->isLocked()) { 8 $ns->unLock(); 9} view plain | print
Zend Framework Session: Automatic Expiration

Zend Framework Session Step By Step Tutorial - Part 6: We can set limited time for a namespace. For this feature, we called namespace expiration. Example, we want to count number of page request by a person in one minute. After 1 minute, he will be counted as new person. So, the code like this: We try at loginform. Open UserController.php within application/controllers. Update loginFormAction(): 1 public function loginFormAction() 2 { 3 4 $ns = new Zend_Session_Namespace('HelloWorld'); 5 6 if(!isset($ns->yourLoginRequest)){ 7 $ns->yourLoginRequest = 1; 8 }else{ 9 $ns->yourLoginRequest++; 10} 11 12$ns->setExpirationSeconds(60); 13 14 $request = $this->getRequest(); 15$this->view->assign('request', $ns->yourLoginRequest); 16$this->view->assign('action', $request->getBaseURL()."/user/auth"); 17 $this->view->assign('title', 'Login Form');
18 $this->view->assign('username', 'User Name'); 19 $this->view->assign('password', 'Password'); 20 21 } view plain | print You can set only at a particular key (e.g, yourLoginRequest): 1$ns->setExpirationSeconds(60,'yourLoginRequest'); view plain | print
