`preg_match` the Whole String in PHP

Question

This thing really confuses me, pardon my ignorance.

I have a var $name in here that I want to be free from number, I don\'t want any digit to be included in

Answer 1

Your regex only checks that there is at least one non-digit. Instead, you need to check that it is only non-digits:

var_dump(preg_match('/^\D+$/',$name));

(^ and $ are the beginning and end of the string. \D means anything not a digit--the opposite of \d. So this only matches non-digits from beginning to end. It doesn't match an empty string. Replace + with * if you want to match an empty string as well).
