Regex for a string used for save a telephone number

Question

I have a question. How should look a regex for the following words: +23456745678 or +29845281058, (with comma) I tried but no result:

if (!preg_match('#^\+[0-9]{11}$#',$string)) {
                    return ("Msisdn $string is incorrect!");
                    break;
                }

Always I get this error. Please help me. Thx in advance

Answer 1

The pattern should be:

'/\+[0-9]{11},?/'

The ^ in the beginning and $ at the end stand for beginning and end of line, which I am not sure if you really want there (my guess is not).

Another option is to use \\d for digit

'/\+\d{11},?/'
