How to validate a Phone Number With `-` and spaces

Question

I want to validate the phone number Like 1-12 -123 using regex and I have tried like

/^[0-9 -]+$/

and

/^[0-9,\- ]+$/

Iam using it like

/^[0-9 -]+$/.test(value)

And it is accepting 0-9 numbers and - also but not accepting the spaces.I have tried in many ways but did'nt got any solution.Can anyone suggest me.Thanks in Advance

@subzero you gave the same that I have asked...Open the link — GautamD31, Oct 21 '13 at 13:01
`/^[0-9 -]+$/` is working for me, it returns true on `1-12 -123`, are you sure the problem is on the regex expression? — aleation, Oct 21 '13 at 13:09
`/^[0-9 -]+$/.test(value)` will not match anything in PHP... `.` is for concatenation ! — Fabien Sa, Oct 21 '13 at 13:12
Which language are you using? Is this JavaScript? PHP? Something else? — Simon Forsberg, Oct 21 '13 at 13:14
@Gautam3164 What about page language, HTML, PHP? And why are you using JS to validate? You (must) know better than anyone else that people can disable JS, and is not a good method to use. Why not use via serverside instead? — Funk Forty Niner, Oct 21 '13 at 13:16
@Gautam3164 Then I don't see the problem `alert(/^[0-9 -]+$/.test("1-12 -123"));` returns true in JSfiddle. Are you **sure** about your value variable? — Simon Forsberg, Oct 21 '13 at 13:18
Fref -ii- I accept you but I just need that in javascript itself — GautamD31, Oct 21 '13 at 13:19
Because none of us has been able to reproduce your problem, I'm voting to close because of the SCCEE reason. — Simon Forsberg, Oct 21 '13 at 13:21
show us the code, I've tried both in php and javascript and it finds the pattern xD — aleation, Oct 21 '13 at 13:21
@Gautam3164 My guess you need to add `return` as in `function validateEmail(value) { var re = /^[0-9 -]+$/; return re.test(value); }` — Funk Forty Niner, Oct 21 '13 at 13:23
My guess is: Your `value` variable is really not what you think it is. — Simon Forsberg, Oct 21 '13 at 13:24
@Gautam3164 Did you [try my last suggestion](http://stackoverflow.com/questions/19495232/how-to-validate-a-phone-number-with-and-spaces#comment28917213_19495232) ? — Funk Forty Niner, Oct 21 '13 at 13:30

you can use [ -0-9]+ (leave a space after the first square bracket) to allow spaces, dashes and numbers

@Gautam3164 Show the code you are using together with the regex. (Edit your question and provide this, do not post that code in a comment) – Simon Forsberg Oct 21 '13 at 13:09
@SimonAndréForsberg see my edit once...BTW I didnt gave any code in my comment – GautamD31 Oct 21 '13 at 13:11
@Gautam3164 sorry, didn't see how much reputation you had :) I guess you're quite used to StackOverflow then so you know better than to post a lot of code in a comment :P – Simon Forsberg Oct 21 '13 at 13:15

What I'd recommend is trimming out the spaces and the - from the field, and then validate the digits only. Because I doubt

-----0-4  023 - 331 34    124
00000                      -
-

etc

should be considered a valid phone-numbers?

And if you then try to make a phone-number regex to take that into considerations you'll either not succeed, or run into an expression that's so complex that it's not maintainable.

So instead trim your input/format your input into a format you control, which you then easily can validate and use that.

If you really want to go a Regular Expression route, I'd think something like

^[1-9]([ \-0-9][0-9]+)+$

is what you're after. (if the number must not start with 0, otherwise replace the first [1-9] with [0-9]) Also change the final + into {0;y} for how many blocks of numbers you allow etc if there's a limit/focus on how many 'blocks' of numbers you allow. Regular expressions can quickly become very complex.

For javascript :

var phoneNumber = "1-12 -123";
var test = /^[0-9 -]+$/.test(phoneNumber);

alert(test); // Here, return true

If you code in PHP, this code will match your phone number.

<?php

$phoneNumber = '1-12 -123';

if(preg_match('/^[0-9 -]+$/', $phoneNumber)) {
    echo "Phone number is valid";
}

Edit: Ok, use the right tag next time.

this one works [0-9 -]+, this doesn't work [0-9- ]+ (order matters)

For spaces you need to put a \s in your alphabet.

/^[0-9\s-]+$/

`\s` is not only a simple space like ' ' but can be a tab, a new line, a carriage return etc. – Fabien Sa Oct 21 '13 at 13:05
`\s` matches more than just spaces, it matches all whitespace characters. – Gerald Schneider Oct 21 '13 at 13:05
**Warning:** \s also includes other types of whitespace! – ComFreek Oct 21 '13 at 13:05
