Phone number validation in PHP

Question

I need to validate phone number in PHP. I have made following regex, but I also need to it to accept numbers starting with plus char, how can I do that?

^[0-9]$         


        

Answer 1

Try this:

/^[\+]?([0-9]*)\s*\(?\s*([0-9]{3})?\s*\)?[\s\-\.]*([0-9]{3})[\s\-\.]*([0-9]{4})[a-zA-Z\s\,\.]*[x\#]*[a-zA-Z\.\s]*([\d]*)/

will match:

+1 ( 111)111-1111, #111

111-111-1111

(111)111-1111 x 1

111.111.1111x1

etc.

Answer 2

use this /^(+\d)\s((\d{3})\s*)*\d{3}(-{0,1}|\s{0,1})\d{2}(-{0,1}|\s{0,1})\d{2}$/;

Answer 3

The regex you provided in your question (^[0-9]$) will only match a one digit phone number.

At the very least you probably need to add the + modifier to allow one or more digits:

^[0-9]+$

To add an optional + at the beginning, you'll need to escape it since + is a special character in regular expressions:

^\+?[0-9]+$

And finally, \d is shorthand for [0-9] so you could shorten the expression to

^\+?\d+$
