Zend Framework Tutorial: Overview of Bootstrap Class Usage

The example in this article describes the usage of Bootstrap class in Zend Framework. Share it with everyone for your reference, the details are as follows:

Zend_Application_Bootstrap_Bootstrapper

Zend_Application_Bootstrap_Bootstrapper is the basic interface that all boot classes must implement. The basic functionality is for configuring, registering resources, bootstrapping (either individual resources or the entire application), and running the application.

Interface method:

Zend_Application_Bootstrap_Bootstrapper Interface

##Zend_Application_Bootstrap_ResourceBootstrapper

Zend_Application_Bootstrap_ResourceBootstrapper is An interface for bootstrapping class loading to register external resources. That is, one or more resources will not be defined directly in the class, but will be introduced through plug-ins. It should be used in conjunction with Zend_Application_Bootstrap_Bootstrapper; Zend_Application_Bootstrap_BootstrapAbstract implements this functionality.

Interface method:

Zend_Application_Bootstrap_ResourceBootstrapper Interface

##Zend_Application_Bootstrap_BootstrapAbstract

Zend_Application_Bootstrap_BootstrapAbstract is An abstract class that provides a common bootstrap basic functionality. It implements Zend_Application_Bootstrap_Bootstrapper and Zend_Application_Bootstrap_ResourceBootstrapper.

Zend_Application_Bootstrap_BootstrapAbstract Methods

#Zend_Application_Bootstrap_Bootstrap

Zend_Application_Bootstrap_Bootstrap is Zend_Application_Bootstrap_BootstrapAbstract specific implementation. Its main function is to register resources and then run the run() method.

In most cases, you can inherit this class or use this class directly according to your boot needs and register resource plug-ins.

Enable Application auto-loading function

In addition, the implementation of this guide provides the function of automatically loading the specified "namespace" or the prefix of the specified resource class

Essentially, it Instantiate a Zend_Application_Module_Autoloader object, and the parameters are the namespace and the directory of the boot class. This feature can be turned on by setting the namespace through the "appnamespace" configuration option.

As an INI example:

Or in XML:

By default, Zend_Tool provides the "Application" namespace.

Alternatively, you can specify the namespace through the $_appNamespace attribute in the bootstrap class.
