php的简单电话号码正则表达式

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?

Answer 1

The following regex works

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

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

Answer 2

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

Answer 3

The problems you are having are:

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

Otherwise, you're good!

Answer 4

[] define character classes. eg "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

eg

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

would be closer to what you want.

Answer 5

/(\(\d{3}+\)+ \d{3}+\-\d{4}+)/ (000) 000-0000

/(\d{3}+\-\d{3}+\-\d{4}+)/ 000-000-0000

Answer 6

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

in Php works for the following

(999) 999 9999

(999) 999-9999

(999) 999-9999

999 999 9999

999 999-9999

999-999-9999
