分享下PHP return语句的另一个作用，在bbPress的代码中看到的一个奇葩使用方法。

一直以为，return只能出现在函数中，直到看了bbPress的代码:

<&#63;php
require_once('./bb-load.php');

bb_repermalink(); // The magic happens here.

if ( $self ) {
if ( strpos($self, '.php') !== false ) {
require($self);
} else {
require( BB_PATH . 'profile-base.php' );
} // www.jb51.net
return;
}
Copy after login

难道 return 还能出现在函数之外？这在C语言是无法想象的。

查了一下 PHP 手册：如果在一个函数中调用 return 语句，将立即结束此函数的执行并将它的参数作为函数的值返回。如果在全局范围中调用，则当前脚本文件中止运行。
