php 反射机制实现代理模式

<?php
class test{
function callprint() {
print_r("onesdf");
}
function test2($args='') {
print_r($args);
}
}
class testDelegator {

if($method=$r->getMethod($name))
{
if($method->isPublic()&&!$method->isAbstract())
{
return $method->invoke($obj,$args);
}
}
}
}
}

$d=new testDelegator(new test());
$d->callprint();
$d->test2('the name of the method is test2','array2');
?>
