<?php

class ClassOne {

     function callClassOne() {

         print "In Class One" ;

     }

}

class ClassOneDelegator {

     private $targets ;

     function __construct() {

         $this ->target [] = new ClassOne ();

     }

     function __call( $name , $args ) {

         foreach ( $this ->target as $obj ) {

             $r = new ReflectionClass ( $obj );

             if ( $method = $r ->getMethod ( $name )) {

                 if ( $method ->isPublic () && ! $method ->isAbstract ()) {

                     return $method ->invoke ( $obj , $args );

                 }

             }

         }

     }

}

$obj = new ClassOneDelegator ();

$obj->callClassOne();

结果：In Class One
