Minor【 PHP框架】6.代理

6.1 代理

　　Minor提供了一个类似于java中InvocationHandler接口和一个Proxy类的代理模式的实现，具体可参考我的这篇文章：http://www.cnblogs.com/orlion/p/5350752.html

　　6.1.1 使用

　　

<span style="color: #0000ff;">class</span> FooController <span style="color: #0000ff;">extends</span><span style="color: #000000;"> Controller
{
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">function</span> bar(<span style="color: #800080;">$productName</span><span style="color: #000000;">)
    {
       
        </span><span style="color: #800080;">$log</span> = <span style="color: #0000ff;">new</span><span style="color: #000000;"> LogHandler();
        </span><span style="color: #800080;">$shop</span> = <span style="color: #0000ff;">new</span><span style="color: #000000;"> Shop();
        </span><span style="color: #800080;">$shopProxy</span> = Proxy::newProxyInstance(<span style="color: #800080;">$shop</span>, <span style="color: #800080;">$log</span><span style="color: #000000;">);
        </span><span style="color: #800080;">$shopProxy</span>->buy(<span style="color: #800080;">$productName</span><span style="color: #000000;">);

    }
}</span>
