php reg exp to check for telephone number

I need a reg exp to check for telephone number, the telephone number goes like this:

400-1889-8989

So the telephone number should include 0-9 and dash(-) only, and it has to start and end with number. Don't know how to write a reg exp... any help would be appreciated! Thanks.

Going by the thought that all telephone numbers would be of the form 000-0000-0000, that is 3 digits followed by -, followed by 4 digits, then a - again and another 4 digits.

The regex will be like this

/[0-9]{3}-[0-9]{4}-[0-9]{4}/

This regex will only return true if the number is like "3-4-4", I mean "932-3434-4232" or "534-3342-4233" 

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

This is a strict interpretation of your requirements (include 0-9 and dash (-) only, and it has to start and end with number):

/^[0-9][0-9-]*[0-9]$/

Do realize that this leaves the door open to a variety of inputs that will not even remotely resemble a phone number, e.g. 00, 0-----9, 666666666666666666666666 and so on.
