How to get first numeric character with preg_match?
===

I have phone number. If the first numeric character of a number is not 1 I need to add it. I can't find out how to do it with preg_match, or is there any other way?

    $first_number = $number;
    if(preg_match('something', $first_number, $result))
    {
    $first_number = '1'. $result[1];
    }
