PHP preg_replace() pattern, string sanitization.
- by Otar
I have a regex email pattern and would like to strip all but pattern-matched characters from the string, in a short I want to sanitize string...
I'm not a regex guru, so what I'm missing in regex?
<?php
$pattern = "/^([\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+\.)*[\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+@((((([a-z0-9]{1}[a-z0-9\-]{0,62}[a-z0-9]{1})|[a-z])\.)+[a-z]{2,6})|(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?)$/i";
$email = 'contact<>@domain.com'; // wrong email
$sanitized_email = preg_replace($pattern, NULL, $email);
echo $sanitized_email; // Should be contact@domain.com
?>
Pattern taken from: http://fightingforalostcause.net/misc/2006/compare-email-regex.php (the very first one...)
