I am trying to create a serial number checker.
Serial Numbers are in ranges
A87594 - A92778
AB34534 - AC23405
B23933 - C344444
I was able to get the numbers to work using range() for the first serial number example, I'm guessing I need to use explode() but I wasn't sure how to explode the letters into a variable and the numbers into a seperate variable.
if($_POST['submit']) {
$snum = $_POST['serial_number'];
// 1952
$jan01_jan07 = range(87594, 92478);
if (in_array($snum, $jan01_jan07)) {
echo 'You have a 1952 Widget';
}
else {
echo 'Your serial number is unknown';
}
}
