I am trying to make a website that you input a list of non check digit IMEI's on one page (below)

and then it submits to this page

$D[]=$imei;

$sum = $D[$i]*2;
//seperate numbers that become double digits
if ($D[$i] > 4) {
//convert int to string
$sumS = (string)$sum;
//clear array
unset($splitt);
//seperate the numbers and add them together
for ($j = 0; $j <= 1; $j++) {
$splitt[]=$sumS[$j];
$sumeven = $sumeven + $splitt[$j];
}
//else just add the single number to the last
} else {

}
// adding odd numbers together

$sum = 0;
for ($i = 0; $i <= 13; $i=$i+2) {

$sumodd = $sumodd + $sum;
}
// add odd and even numbers

//convert int to string

//Split total into two variables

}
if ($split[1] == 0) {
$zero = 0;
$IMEIZERO = $imei.$zero;
//print $IMEIZERO;
} else {
$split[0] = $split[0] + 1;
$totalNew = $split[0]."0";
$chk = $totalNew - $total;
$IMEICHK = $imei.$chk;
//print $IMEICHK;
}

<?php print $IMEICHK OR $IMEIZERO?>
</textarea>
</body>
</html>
However I am having a hard time thinking about how I can make it print or echo more than once and print/echo unique values into the textarea for example if I wanted to get the check digit of the following 14 digit IMEI's 15832859381748 18247395837243 52835621351219 12583582923852
I would like to put them into the first page, press submit and have them on the second page with the check digits on the end. So like this
158328593817484 182473958372434 528356213512196 125835829238525
Any ideas?
Thank you very much
Have the user enter one number per line, then when you receive it, use PHP's explode() function. You'll end up with an array of all the IMEIs.
I couldn't resist the urge to fix the checksum calculation, there are comments inline to explain what some of the functions do.
$imeis = explode("\n", $_POST['IMEI']);
$output = "";
foreach ($imeis as $imei) {
$sum = 0;
//str_split converts strings to arrays
//array_reverse reverses arrays; that is how the checksum should be done
$imeiRev = array_reverse(str_split(trim($imei)));
//loop through each digit in the now-reversed IMEI
foreach ($imeiRev as $i=>$digit) {
if ($i % 2 === 0 && $digit > 4) {
//it's even and greater than 4
$digit = array_sum(str_split($digit * 2));
} elseif ($i % 2 === 0) {
//it's even
$digit = $digit * 2;
}
//add to our running total
$sum += $digit;
}
$sum = str_split($sum * 9);
//array_pop just "pops" the last value off
$checkdigit = array_pop($sum);
//add it to the IMEI
$output .= "$imei$checkdigit\n";
}
