数组在PHP中遍历$ _POST变量

Question

I need to remove double quotes from any possible post value. I currently have this code:

array_walk($_POST, create_function('&$val', '$val = str_replace(chr(34), chr(39), $val);'));    

The problem is that its not working as expected. So if a post input box is set to the following when posted...

A " Test

The resulting post variable I get after running the array walk instead contains a slash chr !?! Ie...

A \' Test

Instead of

A Test

Can anyone suggest what's going on here ?

Answer 1

the code is doing what you ask it to, replace " with '.

to remove the " change your code to

array_walk($_POST, create_function('&$val', '$val = str_replace(chr(34), "", $val);'));

which replaces the " with nothing
