演示用代码如下所示:

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();
?>
