您可以在PHP中一次取消设置()许多变量吗? [英] Can you unset() many variables at once in PHP?

问题描述

我有一个流量很高的社交网站，
我想养成取消设置大数组和mysql对象甚至是一些字符串变量的习惯.

I have a pretty high traffic social network site,
I would like to get into the habit of unsetting large array and mysql object and even some string variables.

因此有可能取消PHP中超过1个项目的设置

So is it possible to unset more then 1 item in PHP

示例:

<?PHP

unset($var1);

// could be like

unset($var1,$var2,$var3);

?>

推荐答案

是.

您的示例将按照您的想象运行. unset() 的方法签名如下:

Your example will work just as you imagine. The method signature for unset() is as follows:

void unset ( mixed $var [, mixed $var [, mixed $... ]] )
