PHP需要修剪所有$ _POST变量 [英] PHP need to trim all the $_POST variables

问题描述

在异常情况下需要您的帮助.我需要修剪所有$ _POST变量.

Need you help in an unusal situation. I need to trim all the $_POST variables.

我有什么方法可以一次完成，即使用一个功能吗?

Is there any way I can do it at a single shot i.e., using a single function?

我知道trim($ _ POST)不会做，我必须做一些类似的功能

I know trim($_POST) won't do, I have to make some function like

function sanatize_post(){
    foreach ($_POST as $key => $val)
        $_POST[$key] = trim($val);
}

但是，如果您还有其他建议或意见，请帮助我.

But, if you have any other suggestion or comment, please help me.

谢谢

推荐答案

将array_walk与自定义函数一起使用

use array_walk with a custom function

$clean_values = array();
array_walk($_POST, 'sanitize_post');

function sanitize_post($item, $key)
{
    $clean_values[$key] = trim($item);
    //optional further cleaning ex) htmlentities
}
