Regex for validating international phone numbers
Here i provide a regex pattern to determines if the phone number is in correct format, the pattern force starting with 3 digits follow by a “-” and 7 digits at the end.Explanation \d = only digit allow = length All phone numbers must in “xxx-xxxxxxx” format.There is another form of regular expression that PHP supports (POSIX extended), but I’m not going to touch on that at all.Consider POSIX extended regular expressions the weaker cousin of PCRE (I’ll likely be flamed for this).Already have an regular express for US domestic phone numbers, but we may get international numbers entered. TIA Garry Yeah I wish i knew more about regular expressions, pretty sure you can do an OR statement so you could pin together an international regex and an standard domestic american number but dont know what to tell you sorry... \d-\d" How would I change this to accomodate both international and domestic US phone numbers?
For instance, for one of my customers, I’m integrating Cisco IP Communicator and Cisco Agent Desktop with CLM in Smart Office such that when customer service representatives receive incoming phone calls from their customers, Smart Office automatically searches for that incoming phone number in CLM and displays a list of possible matches.This includes (555) 321-1234, 555-321-1234, 555 321-1234, 5553211234, 321-1234, and many more (even including formats with extensions).The expression looks like this: Now that we have an expression that will work some magic and validate a phone number, let’s see how to put it into action.If we wanted to do that, we could create three (or four) form fields (one for each element) and restrict the length of those fields.Then, on the server-side, we’d piece them together.
Here’s how to use the regular expression to do just that: will be “4321.” Go ahead and try the code with any US formatted number you can think of. If not, let me know; I’m always willing to revise my code.
