Take out emails and web addresses from form information

[steveclondon]

Hi,

I want to automatically strip out any email addresses and website links that users may enter into a form. Does anyone know of any good classes to do this, as  I am sure I would just be reinventing the wheel if I start making the code for this.

If not any ideas of the best way to go about it will be of great help. I would imagine that I would need to search for the @ symbol and www.  then count the start of the word and end of the word and replace it with a space. I know how to tackle it that way using string replace etc but if there is a quicker or better way please let me know. Would preffer a class that already does this though.

You could do it like this...
[code]<?php
//UNTESTED
$p = array("/\b(http|https|ftp):\/\/((\w+\.)+)\w{2,}(\/?)\b/i","/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i");
preg_replace($p,"",$subject);
?>[/code]
