示例 #1 ReflectionClass::isCloneable()的基本用法
<?php
class NotCloneable {

private function __clone() {
}
}
class Cloneable {
public $var1;
}
$notCloneable = new ReflectionClass('NotCloneable');
$cloneable = new ReflectionClass('Cloneable');
var_dump($notCloneable->isCloneable());
var_dump($cloneable->isCloneable());
?>以上示例将输出
bool(false) bool(true)
