note 31203 added to function.array-rand

Note that the int num_req parameter is the required number of element to randomly select. So if your array has 3 element and num_req=4 then array_rand() will not return anything since it is impossible to select 4 random elements out of an array that only contains 3 elements. Many people think that they will get 3 elements returned but that is of course not the case. -- http://www.php.net/manual/en/function.array-rand.php http://master.php.net/manage/user-notes.php?action=edit+31203 http://master.php.net/manage/user-notes.php?action=delete+31203 http://master.php.net/manage/user-notes.php?action=reject+31203
