Hi guys,

This code will teach you on how to generate a random code using PHP. To generate a new random code, just click the refresh button.

Sample code:

  1. <?php
  2. include('header.php');
  3. ?>
  4. <html>
  5. <body>
  6. <div class="container">
  7. <?php
  8. function randomcode() {
  9. $var = "abcdefghijkmnopqrstuvwxyz0123456789";
  10. srand((double)microtime()*1000000);
  11. $i = 0;
  12. $code = '' ;
  13. while ($i <= 7) {
  14. $num = rand() % 33;
  15. $tmp = substr($var, $num, 1);
  16. $code = $code . $tmp;
  17. $i++;
  18. }
  19. return $code;
  20. }
  21. ?>
  22. <h1>
  23. <?php
  24. echo randomcode();
  25. ?>
  26. </h1>
  27. <br>
  28. <a href="index.php" class="btn btn-info">Refresh</a>
  29. </div>
  30. </body>
  31. </html>

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
