以下为引用的内容：

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();

?>

输出结果：

In Class One

可见，通过代理类ClassOneDelegator来代替ClassOne类来实现他的方法。

同样的，如下的代码也是能够运行的：

class ClassOne {

function callClassOne() {

print "In Class One";

}

}

class ClassOneDelegator {

private $targets;

function addObject($obj) {

$this->target[] = $obj;

}

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->addObject(new ClassOne());

$obj->callClassOne();

?>
