本文实例讲述了php设计模式之装饰模式。分享给大家供大家参考，具体如下：
这种模式创建了一个装饰类，用来包装原有的类，并在保持类方法签名完整性的前提下，提供了额外的功能。
具体装饰(Concrete Decorator)角色：负责给构件对象增加附加的职责。
class RequestHelper{}
abstract class ProcessRequest{
abstract function process(RequestHelper $req);
}
class MainProcess extends ProcessRequest{
function process(RequestHelper $req)
{
print detest_class.": doing something useful with request\n";
}
}
abstract class DecorateProcess extends ProcessRequest{
protected $processRequest;
function __construct(ProcessRequest $pr)
{
$this->processRequest = $pr;
}
}
class LogRequest extends DecorateProcess{
function process(RequestHelper $req)
{
print detest_class.": logging request\n";
$this->processRequest->process($req);
}
}
class AuthenticateRequest extends DecorateProcess{
function process(RequestHelper $req)
{
print detest_class.": authenticating request\n";
$this->processRequest->process($req);
}
}
class StructureRequest extends DecorateProcess{
function process(RequestHelper $req)
{
print detest_class.": structuring request\n";
$this->processRequest->process($req);
}
}
$process = new AuthenticateRequest(new StructureRequest(
new LogRequest(
new MainProcess()
)));
$process->process(new RequestHelper());
Request: authenticating request
StructureRequest: structuring request
LogRequest: logging request
