RE: [PHP] Regex for telephone number

> 123 4567 > 1234567 > +91 44 123 4567 > +91 44 1234567 > 91-44-123 4567 > 91-44-1234567 So, 91441234567 and 9 1 4 4 1 2 3 4 5 6 7 aren't valid? You *could* apply a rule here, but it's fallible. 1. Strip out everything thats not a number (ereg_replace("[^0-9]", "")). 2. Count the number of digits. a. If there's less than 7 digits, its invalid. b. 7 digits is valid, local number format. c. 8, 9, and 10 digit numbers are invalid. d. 11 digits is valid, international format. Of course, if someone has a mobile phone this will fall flat on its face (in Australia, our phone numbers have 8 digits and our mobiles have 10 digits - this is the same in a number of countries). My advice, check that there's at least 7 digits and let it go. Jason -- Jason Murray jasonm@melbourneit.com.au Web Design Team, Melbourne IT Fetch the comfy chair!
