Configuration

While Zend Framework is itself configurationless, you often need to configure your application. The default configuration is placed in application/configs/application.ini, and contains some basic directives for setting your PHP environment (for instance, turning error reporting on and off), indicating the path to your bootstrap class (as well as its class name), and the path to your action controllers. It looks as follows:

; 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

Several things about this file should be noted. First, when using INI-style configuration, you can reference constants directly and expand them; APPLICATION_PATH is actually a constant. Additionally note that there are several sections defined: production, staging, testing, and development. The latter three inherit settings from the "production" environment. This is a useful way to organize configuration to ensure that appropriate settings are available in each stage of application development.
