note 93517 added to function.array-rand

webmaster at askapache dot com's note on 2 May 2009 has a couple potential off-by-one errors by using sizeof()'s return value as the second argument for the rand() calls. You would need to subtract one from sizeof()'s return value: <?php $array = array('one', 'two', 'three'); $idx = rand(0, sizeof($array) - 1); echo $array[$idx]; ?> ---- Server IP: 209.41.74.194 Probable Submitter: 72.67.36.93 ---- Manual Page -- http://www.php.net/manual/en/function.array-rand.php Edit -- https://master.php.net/note/edit/93517 Del: integrated -- https://master.php.net/note/delete/93517/integrated Del: useless -- https://master.php.net/note/delete/93517/useless Del: bad code -- https://master.php.net/note/delete/93517/bad+code Del: spam -- https://master.php.net/note/delete/93517/spam Del: non-english -- https://master.php.net/note/delete/93517/non-english Del: in docs -- https://master.php.net/note/delete/93517/in+docs Del: other reasons-- https://master.php.net/note/delete/93517 Reject -- https://master.php.net/note/reject/93517 Search -- https://master.php.net/manage/user-notes.php
