PHP反射机制例子

<?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
