代理在 PHP 中的实现

Proxy is a structural design pattern that provides an object that acts as a substitute for a real service object used by a client. A proxy receives client requests, does some work (access control, caching, etc.) and then passes the request to a service object.

The proxy object has the same interface as a service, which makes it interchangeable with a real object when passed to a client.

在 PHP 中使用模式

Complexity: Average

Popularity: Low

Usage examples: While the Proxy pattern isn't a frequent guest in most PHP applications, it's still very handy in some special cases. It's irreplaceable when you want to add some additional behaviors to an object of some existing class without changing the client code.
