Head First Zend Framework - Part 1 Project & Application
3 likes3,489 views
Zend Framework provides tools for creating PHP web applications. The zf script is used to generate a project skeleton and configure resources. The Zend_Application loads configuration from application.ini, initializes the bootstrap class, and runs the application. The bootstrap class initializes custom resources. Common resources like the front controller, database, and view are initialized through Zend_Application_Resource classes, which get configuration options from application.ini. This allows flexible configuration and initialization of an MVC application in Zend Framework.

# 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](https://image.slidesharecdn.com/headfirstzendframework-part1-100716074949-phpapp01/85/Head-First-Zend-Framework-Part-1-Project-Application-4-320.jpg)

- 13. includePaths in application.ini Use "set_include_path" function. Prepend to "include_path". "library" is identity for configuration.
- 14. bootstrap in application.ini To load Bootstrap class.
- 15. 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 "; } }
- 16. appnamespace in application.ini Define the autoloader prefix of models, form, etc.

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

Will initialize Zend_Application_Resource_Db
- 21. Autoloadernamespaces in application.ini Register the prefix of library. Autoloadernamespaces[] = "My_"
