CodePudding user response：

You can use preg_replace for this with a combination of non word characters \W and _ like below:

<?php

$string = "IT_Support_/_Help_Desk";

echo preg_replace('/[_\W] /', ' ', $string);

CodePudding user response：

$string = "IT_Support_/_Help_Desk";
$string = preg_replace('~[\\\\\/:*?"<>|_]~', ' ', $string);

echo $string;
