note 54460 added to function.shuffle

Vladimir's routine to sort an associated array is great, but one may want to add a clause to check that the array is not empty: if (count($shuffle_me)>0) { code } This is because array_rand does not like to pick zero entries out of an empty array (at least not in PHP 4.x). ---- Manual Page -- http://www.php.net/manual/en/function.shuffle.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54460 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54460&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54460&report=yes Search -- http://master.php.net/manage/user-notes.php
