Head First Zend Framework Part 1 - Project & Application Jace Ju

Install  Get Zend Framework from svn repository. # cd /path/to/library/php # svn co http://framework.zend.com/svn/framework/standard/tags/release- 1.10.x/library/Zend (add ZF_HOME = /path/to/ZF, example: /usr/local/ZF) # cd $ZF_HOME # svn co http://framework.zend.com/svn/framework/standard/tags/release-1.10.x/bin # cd bin # ln –s $ZF_HOME/bin/zf.sh $ZF_HOME/bin/zf

Setup  Create config of zf script # zf create config Successfully written Zend Tool config. It is located at: /usr/local/ZF/.zf.ini (Bug in ZF 1.10.6.) # vi /usr/local/ZF/.zf.ini php.includepath change to php.include_path # zf show config User Configuration: /usr/local/ZF/.zf.ini `-- php `-- include_path: /usr/local/lib/php:/var/lib/php:.

What is zf script  Help info # zf ? Usage: zf [--global-opts] action-name [--action-opts] provider-name [--provider-opts] [provider parameters ...] Note: You may use "?" in any place of the above usage string to ask for more specific help information. Example: "zf ? version" will list all available actions for the version provider. ... (ignore) ... DbTable zf create db-table name actual-table-name module force-overwrite Note: There are specialties, use zf create db-table.? to get specific help on them. ProjectProvider zf create project-provider name actions

Create Project  Build a project skeleton # cd /path/to/wwwroot # zf create project zf_test Creating project at /path/to/wwwroot/zf_test Note: This command created a web project, for more information setting up your VHOST, please see docs/README # cd /path/to/wwwroot/zf_test # zf show project.info Working with project located at: /path/to/wwwroot/zf_test # zf show profile ProjectDirectory ProjectProfileFile ... (ignore) ... TestsDirectory TestPHPUnitConfigFile TestApplicationDirectory TestApplicationBootstrapFile TestLibraryDirectory TestLibraryBootstrapFile

Setup Project  Setup VirtualHost in Apache config file <VirtualHost *:80> DocumentRoot "/path/to/wwwroot/zf_test/public" ServerName zf_test # This should be omitted in the production environment SetEnv APPLICATION_ENV development <Directory "/path/to/wwwroot/zf_test/public"> Options Indexes MultiViews FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost>  http://zf_test/

Create Protable Project  Change position of index.php and .htaccess # cd /path/to/wwwroot/zf_test # cp public/.htaccess . # cp public/index.php . # vi public/.htaccess RewriteEngine Off # vi public/index.php <?php header('HTTP/1.1 403 Forbidden'); # vi .htaccess SetEnv APPLICATION_ENV development # vi index.php '/../application' change to '/application'  http://localhost/zf_test/

Project Structure  application  configs  controllers  models  views  helpers  scripts  docs  library  public  tests

Application  Zend_Application  Zend_Application_Bootstrap  Zend_Application_Resource

Zend_Application  Load Configuration.  Initialize bootstrap.  Run. # cd /path/to/wwwroot/zf_test # vi index.php ... (ignore) ... // Create application, bootstrap, and run $application = new Zend_Application( APPLICATION_ENV, APPLICATION_PATH . '/configs/application.ini' ); $application->bootstrap() ->run();

application.ini  Configuration section. # cd /path/to/wwwroot/zf_test # vi application/configs/application.ini [production] phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" appnamespace = "Application" resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers" resources.frontController.params.displayExceptions = 0 [staging : production] [testing : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 [development : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 resources.frontController.params.displayExceptions = 1

phpSettings in application.ini  Use "ini_set" function.  See http://www.php.net/manual/en/ini.list.php.

includePaths in application.ini  Use "set_include_path" function.  Prepend to "include_path".  "library" is identity for configuration.

bootstrap in application.ini  To load Bootstrap class.

Zend_Application_Bootstrap  Initialize custom resources for project. # cd /path/to/wwwroot/zf_test # vi application/Bootstrap.php <?php class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { protected function _initResource1() { $this->bootstrap('resource2'); // Initialize Resource 2 first. echo "Initialize Resource 1n"; } protected function _initResource2() { echo "Initialize Resource 2n "; } }

appnamespace in application.ini  Define the autoloader prefix of models, form, etc.

resources in application.ini  Load common resources.  Define resource options.

FrontController Resource  Initialize Front Controller.  frontController.controllerdirectory  call Zend_Controller_Front::setControllerDirectory()  frontController.params  call Zend_Controller_Front::setParams()

Zend_Application_Resource  Common Resources  Front Controller  Router  Database  View  Session  Layout  Log  ...  More flexible then Bootstrap::_init<Resource> method.

Example: Database Resource  Initialize Custom Resources for Project # cd /path/to/wwwroot/zf_test # zf configure db-adapter "adapter=mysqli&username=uname&password=mypass&dbname=mydb" A db configuration for the production section has been written to the application config file. # vi application/configs/application.ini [production] ... (ignore) ... resources.db.adapter = "mysqli" resources.db.params.username = "uname" resources.db.params.password = "mypass" resources.db.params.dbname = "mydb" ... (ignore) ...  Will initialize Zend_Application_Resource_Db

Autoloadernamespaces in application.ini  Register the prefix of library. Autoloadernamespaces[] = "My_"

pluginPaths in application.ini  Register the prefix and path of plugin classes.  Resolve loading order of plugin. pluginPaths.My_Application_Resource_ = "My/Application/Resource"

Summary  Zend_Application  Load configuration.  Set bootstrap and run.  Zend_Application_Bootstrap  Initialize resources.  Zend_Application_Resource  Get options from configuration.  Initialize controller, view, database, etc.
