PHP 反射机制实现动态代理的代码

<?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();
?>

<?php
