note 75690 added to function.array-rand

To add to asp at cyberlin dot eu's comment. Not only will it return NULL but it will also trigger a warning, and not only if the number of elements requested is too large to be satisfied by the array but also if it is zero. The warning message sums the situation up: "Second argument has to be between 1 and the number of elements [inclusive] in the array". ---- Server IP: 203.89.181.184 Probable Submitter: 60.234.168.92 ---- Manual Page -- http://www.php.net/manual/en/function.array-rand.php Edit -- https://master.php.net/note/edit/75690 Del: integrated -- https://master.php.net/note/delete/75690/integrated Del: useless -- https://master.php.net/note/delete/75690/useless Del: bad code -- https://master.php.net/note/delete/75690/bad+code Del: spam -- https://master.php.net/note/delete/75690/spam Del: non-english -- https://master.php.net/note/delete/75690/non-english Del: in docs -- https://master.php.net/note/delete/75690/in+docs Del: other reasons-- https://master.php.net/note/delete/75690 Reject -- https://master.php.net/note/reject/75690 Search -- https://master.php.net/manage/user-notes.php
