Re: Regular Expression for a UK mobile phone number

you should also be considering spaces, leading zeros, brackets, dashes & international notation. /^(((\+|00)[- ]?[0-9]{2,3}[- ]?(\(0\))?[- ]?[1-9]{1}[0-9]{1,})|(0[1-9]{1}[0-9]{1,}))[- ]?(([0-9]{7,})|([0-9]{3}[ -]{1}[0-9]{4}))$/ line-wrapping is unintentional, no garantees as to how good it is.

I am trying to create a regular expression for a mobile phone number. The number must be 12 digits long(0-9) and begin with 447 and have no spaces. So far I have come up with this but it keeps telling me the number is invalid even when its correct!

Try this: $regexp = "/447[0-9]{9}/"; if($_POST[mobile_number] != ''){ if(!preg_match( $regexp, $_POST[mobile_number] )){

     $error = "Invalid Mobile Number";

header("Location:edit_rep.php?error=$error&rep_id=".$_GET[rep_id]."&client_i d=".$_GET[client_id]."&rep_name=".$_GET[rep_name]."&client_name=".$_GET[clie nt_name]."");

    exit;

} } Also, your regexp is a little permissive; you can anchor it like so: $regexp = "/^447[0-9]{9}$/"; --------------------------------------------------------------------- michal migurski- contact info and pgp key:

Thanks for your reply Michal, but the regular expression still seems to reject the number...
