will the below preg_match work for numbers entered like:
1111-1111-1111-1111
1111 1111 1111 1111
preg_match = /^\(?([0-9]{4})\)?[- ]?([0-9]{4})[- ]?([0-9]{4})[- ]?([0-9]{4})$/

Thanks for the link but I cannot follow it. Way too much going on. – user7104290 Apr 07 '17 at 14:21

The right panel offers an explanation of what everything does. If it is always 4 groups with optional `-` or space separator you could do `^(\d{4}(?:[- ]|$)){4}$`. – chris85 Apr 07 '17 at 14:28
