note 120048 added to function.array-rand

if you're looking for a cryptographically secure variant (as of speaking, php uses mt_rand), i made this. (limitations: it has no $num parameter. it requires php>=7) <?php function csarray_rand(array $arr){ $keys=array_keys($arr); $count=count($keys); if($count===0){ //Contrary to documentation, PHP 4 and 5 and 7, up to php 7.1.0alpha3 does not actually return any warning when the array is empty and $num=NULL (and further contradicting the documentation, its NULL by default, not 1, and they are treated differently, 1 gives error, NULL does not.) ... 7.1.0beta1 does throw an error however... follow their example? if(version_compare(PHP_VERSION,'7.1.0beta1','>=')){ trigger_error('Warning: csarray_rand(): Array is empty',E_USER_ERROR); } return NULL; } $csrand=random_int(0,count($keys)-1); return $keys[$csrand]; } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 88.88.19.218 ---- Manual Page -- http://php.net/manual/en/function.array-rand.php Edit -- https://master.php.net/note/edit/120048 Del: integrated -- https://master.php.net/note/delete/120048/integrated Del: useless -- https://master.php.net/note/delete/120048/useless Del: bad code -- https://master.php.net/note/delete/120048/bad+code Del: spam -- https://master.php.net/note/delete/120048/spam Del: non-english -- https://master.php.net/note/delete/120048/non-english Del: in docs -- https://master.php.net/note/delete/120048/in+docs Del: other reasons-- https://master.php.net/note/delete/120048 Reject -- https://master.php.net/note/reject/120048 Search -- https://master.php.net/manage/user-notes.php
