Re: [PHP] Reformatting phone number string from user input

Thanks John,

That does look a lot tidier. I tried a similar approach early on, but was
trying to specifically match '(' and ')' and was running into lots of
trouble with my syntax, in specific, properly escaping \( and \) so they
were not treated as paranthesis/operators/whatever. This is much simpler. I
like simple :)

Now I can focus on inserting a default area code, if the user does not ;)

Salut,
Verdon
