Zend Framework Tutorial: Overview of Bootstrap class usage, zendbootstrap

This article describes the usage of Bootstrap class in Zend Framework with examples. 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 a single resource or the entire application), and running the application.

Interface methods:

Zend_Application_Bootstrap_Bootstrapper Interface

Method	Return Value	Parameters	Description
__construct( $application )	Void	$application: Required. Accept a Zend_Application or a Zend_Application_Bootstrap_Bootstrapper object as the only parameter.	Construction method. Accepts one parameter, which must be a Zend_Application object or another boot object.
setOptions( array $options)	Zend_Application_Bootstrap_Bootstrapper	$options: Required. Configuration options array	Usually, options can be matched and mapped to the corresponding setter; otherwise, the options will just be stored for easy retrieval later
getApplication()	Zend_Application |Zend_Application_Bootstrap_Bootstrapper	N/A	Get application instance
getEnvironment()	String	N/A	Get environment
getClassResources()	Array	N/A	Get available resources
bootstrap($resource = null)	Mixed	$resource: Optional.	If $resource is empty, register all resources . If it is a string, register the specified resource; if it is an array, only register the specified resource.
run()	Void	N/A	Execute boot.

Zend_Application_Bootstrap_ResourceBootstrapper

Zend_Application_Bootstrap_ResourceBootstrapper is an interface used to bootstrap 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 methods:

Zend_Application_Bootstrap_ResourceBootstrapper Interface

Method	Return Value	Parameters	Description
registerPluginResource($resource, $options = null)	Zend_Application_Bootstrap_ResourceBootstrapper	$resource: Required, the requirement is the resource name. or Zend_Application_Resource_Resource object $options: Optional. Array or Zend_Config object, passing the instance of the resource to be registered.	Used to register resource classes and pass resources through optional options
unregisterPluginResource($resource)	Zend_Application_Bootstrap_ResourceBootstrapper	$resource: Required. Unregister the name of the resource	Delete plug-in resources
hasPluginResource($resource)	Boolean	$resource: Required. Resource name.
getPluginResource($resource)	Zend_Application_Resource_Resource	$resource: Required. Resource name
getPluginResourceNames()	Array	N/A
setPluginLoader(Zend_Loader_PluginLoader_Interface $loader)	Zend_Application_Bootstrap_ResourceBootstrapper	$loader: Required.
getPluginLoader()	Zend_Loader_PluginLoader_Interface	N/A

Zend_Application_Bootstrap_BootstrapAbstract

Zend_Application_Bootstrap_BootstrapAbstract is an abstract class that provides a common basic boot function. It implements Zend_Application_Bootstrap_Bootstrapper and Zend_Application_Bootstrap_ResourceBootstrapper.

Zend_Application_Bootstrap_BootstrapAbstract Methods

Method	Return Value	Parameters	Description
__construct($application)	Void	$application: Required.	Accepts either a Zend_Application or a Zend_Application_Bootstrap_Bootstrapper object as the sole argument.
setOptions(array $options)	Zend_Application_Bootstrap_Bootstrapper	$options: Required. Options array	All options can be mapped to option-specified setters, Otherwise, the option will simply be stored for later lookup For example, if you define a setFoo() method in an extension class, you can pass the value through the foo option Two additional, special options are also available. pluginPaths is used to specify the resource plug-in path prefix, which should be an associative array of classes prefixed with the file system path. Resources are used to specify resource plug-ins and should include configuration options for plug-in resource instances.
getOptions()	Array	N/A
hasOption($key)	Boolean	$key: Required. .
getOption($key)	Mixed	$key: Required.	Does not exist Returns NULL
setApplication(Zend_Application | Zend_Application_Bootstrap_Bootstrapper $application)	Zend_Application_Bootstrap_BootstrapAbstract	$application: 必填.
getApplication()	Zend_Application |Zend_Application_Bootstrap_Bootstrapper	N/A
getEnvironment()	String	N/A
getClassResources()	Array	N/A
getContainer()	Object	N/A	Get the container in which the resource is stored. If there is no container, you can register it through Zend_Registry and then return a Zend_Registry instance.
setContainer($container)	Zend_Application_Bootstrap_BootstrapAbstract	$container,Required. Container object that stores resource objects
hasResource($name)	Boolean	$name, Required. Resource name
getResource($name)	Mixed	$name, Required. Resource name
bootstrap($resource = null)	Mixed	$resource: Optional.	If $resource is empty, register all resources . If it is a string, register the specified resource; if it is an array, only register the specified resource.
run()	Void	N/A
__call($method, $args)	Mixed	$method: Required. Method name. $args: Required. Method parameter array.	For convenience, you can use 'bootstrap()' instead of bootstrap() to guide the registered resources.

Zend_Application_Bootstrap_Bootstrap

Zend_Application_Bootstrap_Bootstrap is the specific implementation of Zend_Application_Bootstrap_BootstrapAbstract. 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 bootstrap implementation provides the ability to automatically load a specified "namespace" or a prefix of a specified resource class

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

As an INI example:

appnamespace = "Application"

Or in XML:

<appnamespace>Application</appnamespace>

By default, Zend_Tool provides the "Application" namespace.

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

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
   protected $_appNamespace = 'Application';
}
