The documentation for preg_replace says the function supports four arguments: pattern, replacement, subject, and limit. However, PHP (4.0.1pl2) does not appear to support the last argument, limit.

Script:

<?php
   $subject = "The tiger ate plants while a tiger watched.";
   echo preg_replace("/tiger/", "giraffe", $subject, 1);
?>

Expected output:

   The giraffe ate plants while a tiger watched.

Actual output:

   Warning: Wrong parameter count for preg_replace() in dir/file.php on line 2


phpinfo() shows:
