note 54851 added to function.dechex

a bugfix for admin AT bobfrank DOT org' s post The original was: <?php function zeropad($num, $lim) { return (strlen($num) >= $lim) ? $num : zeropad("0" . $num); } ?> I couldn't get it to work, kept getting a "Missing argument 2 for zeropad()" error, even though I called the function with both arguments -- then I noticed the recursive part, and the missing $lim argument. The code that works is: <?php function zeropad($num, $lim) { return (strlen($num) >= $lim) ? $num : zeropad("0" . $num, $lim); // $lim was missing from the recursive call // the function will prefix $num with a zero and recursively call itself // each recursive call, $num gets one digit bigger until strlen of $num equals $lim } ?> ---- Manual Page -- http://www.php.net/manual/en/function.dechex.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54851 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54851&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54851&report=yes Search -- http://master.php.net/manage/user-notes.php
