An interesting situation arises when you have O'Brien etc .. I remove the ' since it causes way more trouble than its worth. But if you want to include it simply add \' to the masking string. @Smith

the solution is already described above
$username = (preg_replace(“/[^A-Za-z0-9\s\s+\-]/”, “”, $username));
