Help with Repeating

[rel]

Basicly I need something that repeats itself about 90,000 times.

The code is.

<?
  include("ccval.php");

  $Number = "5105 1051 0510 5100"; // MasterCard test number

  $Result = ccval($Number);
  if ($Result) {
    Print "Good Card.";
  }
  else {
    if (is_int($Result)) echo "Bad Date.";
    else echo "Bad Number";
  }
?>

CCVAL.php

//  The Luhn formula works right to left, so reverse the number.
    $Num = strrev($Num);

$Total = 0;

for ($x=0; $x<strlen($Num); $x++) {
  $digit = substr($Num,$x,1);

//    If it's an odd digit, double it
      if ($x/2 != floor($x/2)) {
        $digit *= 2;

//    If the result is two digits, add them
        if (strlen($digit) == 2)
          $digit = substr($digit,0,1) + substr($digit,1,1);
      }

//    Add the current digit, doubled and added if applicable, to the Total
      $Total += $digit;
    }

//  If it passed (or bypassed) the card-specific check and the Total is
//  evenly divisible by 10, it's cool!
    if ($GoodCard && $Total % 10 == 0) return true; else return false;
  }
?>

I need $number to be replaced by a number from a .txt file , go through the ccval process then move on to the next number in the text file..

The text file looks like this.

93286892386236
26893869289623
32896892386232
96238968923689
32690389026923

But it has 90,000 numbers and I cannot enter each by myself. Thanks

Is each line in the file a separate card number? You have only 12 digits on each line of the text file but sixteen in the sample card number--should there be 16 digits in each card number?

Also, how do you want the output to be presented? For 90,000 cards it might be useful to have it display the results as a text file of all good numbers or all bad numbers, etc.

Each line is corrected by a seperated card number. Yes the card numbers will all be 16 digits. If you can have it display results as a text file for all good that would be great also. if not it can just print to browser and Ill copy/paste.

This is the script I came up with. Valid card numbers are written to good_cards.txt while invalid card numbers are written to bad_cards.txt. Make sure the directory the script is located in is writable by the webserver.

include("ccval.php");

//define files. $input should be the name of
//the file with the card numbers.
$inputf="input.txt";
$goodf="good_cards.txt";
$badf="bad_cards.txt";


//file handles for each of these files
$inputh = fopen($inputf, "r");
$goodh= fopen($goodf, "a");
$badh=fopen($badf,"a");

//loops through input file
while (!feof($inputh)) {
   $Number= fgets($inputh, 4096);
   $Number=str_replace("\n","",$Number); //remove \n line break on each number
   if (ccval($Number)) {
	print "$Number<br />";
	fwrite($goodh,$Number." ");
   } else {
	fwrite($badh,$Number." ");
    }
}

fclose($inputh);
fclose($goodh);
fclose($badh);

Thanks. I appreciate you helping me. You want any money through paypal?

Does the script do everything you want? Notice that I dropped this line from the script:

if (is_int($Result)) echo "Bad Date."; 

As far as I could tell, it could never be true, as $Result is a true/false value, so is_int($Result) will always return false. What is this line supposed to do?

And no, no payment is necessary. We do this for the fun and challenge, not the profit 😃

I really dont care about the bad numbers. and I can work it from here just needed a basic layout just like you provided cause I had no clue on where to start. Thanks though

Also that line was to make sure the exp date was valid. I dont use it no more and just forgot to take it out.

[Matt_Kindig]

One thing I forgot to mention: Whenever you load this script, it will append the results onto the existing good_cards.txt and bad_cards.txt files, so you probably want to clear these files before loading this page again.
