implements Phalcon\DiInterface, ArrayAccess
Phalcon\Di 是一个实现了服务的依赖 注入/业务定位(Service Location) 的组件，并且它本身也是一个这样的容器。由于Phalcon 高度解耦，Phalcon\Di是框架中必不可少的组件。开发者同样可以使用这个组件来注入依赖关系，并且管理程序中使用的不同的类的全局实例。这个组件基本上实现了 控制反转 模式。对象使用setter 或构造函数 不接收它的依赖项，而请求服务的依赖注入。这减少整体的复杂性，因此组件内只有一种方式来获取必要的依赖项。此外，这种模式增加了代码的可预测性，因此使得它不易出错。
<?php
$di = new \Phalcon\Di();
//Using a string definition
$di->set("request", "Phalcon\Http\Request", true);
//Using an anonymous function
$di->set("request", function(){
return new \Phalcon\Http\Request();
}, true);
$request = $di->getRequest();
方法
public __construct ()
Phalcon\Di 的构造函数 | Phalcon\Di constructor
public setInternalEventsManager (unknown $eventsManager)
设置内部事件管理器 | Sets the internal event manager
public getInternalEventsManager ()
返回内部事件管理器 | Returns the internal event manager
public set (unknown $name, unknown $definition, [unknown $shared])
注册一个服务在服务容器中 | Registers a service in the services container
public setShared (unknown $name, unknown $definition)
注册一个“长期共享”服务在服务容器中 | Registers an “always shared” service in the services container
public remove (unknown $name)
删除服务容器中的一个服务，它会同时删除服务创建的任何共享过的实例。 | Removes a service in the services container It also removes any shared instance created for the service
public attempt (unknown $name, unknown $definition, [unknown $shared])
尝试在服务容器中去注册一个服务 ，仅在之前没有注册过相同名字的时候才会注册成功。 | Attempts to register a service in the services container Only is successful if a service hasn”t been registered previously with the same name
public setRaw (unknown $name, unknown $rawDefinition)
设置服务使用原始定义(Falcon\Di\Service) | Sets a service using a raw Phalcon\Di\Service definition
public getRaw (unknown $name)
无返回（上面设置的）一个没有解析的原始服务数据 |Returns a service definition without resolving
public getService (unknown $name)
返回一个 Phalcon\Di\Service 实例 |Returns a Phalcon\Di\Service instance
public get (unknown $name, [unknown $parameters])
基于配置 解析服务 | Resolves the service based on its configuration
public mixed getShared (string $name, [array $parameters])
解析一个服务，解析过的服务已存储在 DI 里，这个服务后来的请求将会返回相同的实例。 | Resolves a service, the resolved service is stored in the DI, subsequent requests for this service will return the same instance
public has (unknown $name)
检查DI是否包含所述服务 | Check whether the DI contains a service by a name
public wasFreshInstance ()
检查最后一个服务是否已存在或者通过 getShared 获取生成了新的实例 | Check whether the last service obtained via getShared produced a fresh instance or an existing one
public getServices ()
返回DI中已注册的服务 | Return the services registered in the DI
public offsetExists (unknown $name)
检查是否使用数组语法注册过 | Check if a service is registered using the array syntax
public boolean offsetSet (string $name, mixed $definition)
允许使用数组语法注册共享服务 | Allows to register a shared service using the array syntax
<?php $di["request"] = new \Phalcon\Http\Request();
public mixed offsetGet (string $name)
允许使用数组语法来获得一个共享服务 | Allows to obtain a shared service using the array syntax
<?php var_dump($di["request"]);
public offsetUnset (unknown $name)
使用数组语法从服务容器中移除一个服务 | Removes a service from the services container using the array syntax
public mixed __call (string $method, [array $arguments])
使用 setters/getters 设置或获取服务的 魔术方法 | Magic method to get or set services using setters/getters
public static setDefault (unknown $dependencyInjector)
设置一个默认依赖注入容器来获取到静态方法 | Set a default dependency injection container to be obtained into static methods
public static getDefault ()
返回最后一个创建的DI | Return the lastest DI created
public static reset ()
重置内部默认的DI | Resets the internal default DI
