PHP中的析构函数可预测吗？ [英] Is destructor in PHP predictable?

问题描述

PHP中的类析构函数可预测吗？像许多语言一样，何时调用析构函数？

Is a class destructor in PHP predictable? When is the destructor called?

当对象超出范围时，是否会立即调用类析构函数？

Like in many languages, will a class destructor be called as soon as the object goes out of scope?

推荐答案

PHP 5引入了析构函数概念
，类似于其他
面向对象语言，例如
C ++。一旦删除了对
特定对象的所有引用，或者当
该对象被显式销毁时，或在关闭顺序中以任何顺序调用
时，将立即调用
的析构函数方法。 p>

PHP 5 introduces a destructor concept similar to that of other object-oriented languages, such as C++. The destructor method will be called as soon as all references to a particular object are removed or when the object is explicitly destroyed or in any order in shutdown sequence.
