You can use the following PHP functions to verify whether a card number is a credit card:
function Validatecard ($cardnumber) { $cardnumber = preg_replace ("/\d|\s/", "", $cardnumber); # Strip any non-digits $cardlength = strlen ($cardnumber); if ($cardlength! = 0) { $parity = $cardlength% 2; $sum
You can use the following PHP function to verify that a card number is a credit card:
function Validatecard ($cardnumber)
{
$cardnumber = preg_replace ("/\d|\s/", "", $cardnumber); # Strip any non-digits
$cardlength = strlen ($cardnumber);
if ($cardlength!= 0)
{
$parity = $cardlength% 2;
