Can anyone tell me if there are similar functions in php as javascript
isNaN, or do I just have to do a
if (preg_match('/([EMAIL PROTECTED]&*()_=+|\?/><,.;:{}-])/',
$_POST['Personal_Hotel_CC_Number']) == 0){}
I know the above doesn't work, would there be an easier way for me to
find if any of the chars are not numbers?
I could do:
if (preg_match_all("/([0-9])/", $var, $match) == 16){}
But AMEX cards are only 15 digits...
It's for credit card verification.
Thanks,
