如何在PHP中为函数加上别名? [英] How to alias a function in PHP?

问题描述

是否可以在PHP中使用其他名称对函数进行别名?假设我们有一个名为sleep的函数.有没有办法创建名为wait的别名?

Is it possible to alias a function with a different name in PHP? Suppose we have a function with the name sleep. Is there a way to make an alias called wait?

现在我正在这样做:

function wait( $seconds ) {
    sleep($seconds);
}

推荐答案

仅PHP 5.6 +

从PHP 5.6开始有可能通过导入功能为函数添加别名:

PHP 5.6+ only

Starting with PHP 5.6 it is possible to alias a function by importing it:

use function sleep as wait;
