Read the following code .. An error occurs when you run it.. (there will be white-screen in my codes.) Chinese : 如果你能看懂中文.那最好不过了. 上面的代码我认为__destruct被继承之后, 会导致下面两个类的对象在释放时出现无法找到static $childs的错误. 但是在我的代码里面他确实没有出现这个错误, 反而运行了很久之后出现了白屏. 看上去很像一个死循环. Test script: --------------- error_reporting(E_ALL); ini_set('display_errors', 'on'); abstract class Father { private static $childs = array(); public static function getChild( $child ) { if (!array_key_exists("$child", self::$childs)) { self::$childs["$child"] = new $child; } return self::$childs["$child"]; } public function __destruct() { foreach (self::$childs as $i => $child) { self::$childs[$i] = $child = null; } } } class Child1 extends Father {} class Child2 extends Father {} $child1 = Father::getChild('Child1'); $child2 = Father::getChild('Child2'); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=53289&edit=1
