Simple phone number regex for php

Question

I've been looking for a simple phone number regex that will match just this format: (XXX) XXX-XXXX <---with the parentheses and the space after them required

For the life of me, I can't figure out why this wont work (This was one that I tried making myself and have been tinkering with for hours):

^[\(0-9\){3} [0-9]{3}-[0-9]{4}$

I've looked everywhere online for a regex with that particular format matching to no avail. Please help?

well, that's actually not what I have. It's really /^$[0-9]${3} [0-9]{3}-[0-9]{4}$/ — Joanne DeBiasa, Oct 28 '12 at 17:39
OK, I guess it's taking out the backslashes that I had in it for some reason — Joanne DeBiasa, Oct 28 '12 at 17:40

Just so you know, i haven't personally written a phone number like `(###) ###-####` in maybe 10 years. Now that many phone services require or at least support entering the area code as part of the number, it seems a bit of a relic. `###-###-####` makes more sense. — cHao, Oct 28 '12 at 17:54

The following regex works

^\(\d{3}\) \d{3}-\d{4}$

^ = start of line
\( = matches parenthesis open
\d = digit (0-9)
\) = matches parenthesis close

here's a working one

/^\(\d{3}\) \d{3}-\d{4}\s$/

the problems with your's:

to match digits just use \d or [0-9] (square brackets are needed, you've forgot them in first occurence) to match parenthesis use $ and $. They have to be escaped, otherwise they will be interpreted as match and your regex won't compile

The problems you are having are:

You need to escape special characters (like parentheses) with a backslash, like this: \(
You have an unclosed square bracket at the beginning.

Otherwise, you're good!

[] define character classes. e.g. "at this one single character spot, any of the following can match". Your brackets are misaligned:

^[\(0-9\){3} [0-9]{3}-[0-9]{4}$
 ^---no matching closer

e.g.

^[0-9]{3} [0-9]{3}-[0-9]{4}$

would be closer to what you want.

What is the purpose of `?` after `\d{4}`. This regex is matching `(1234567890` or `123) -456 -7890`. – Toto Jun 09 '20 at 12:25
