note 83100 added to function.array-rand

"As of PHP 4.2.0, there is no need to seed the random number generator with srand() or mt_srand() as this is now done automatically." Do not trust in this! I tried to fill a database with 100.000 unique id's (in a loop). Each id 7 chars long with a numeric-loweralpha charset. When it came to around ~17.500 queries, the array_rand() function was unable to generate a new unique id from the charset. I don't think it's a bug. However, make sure to seed the random number generator by yourself. Either by adding _ srand((float) microtime() * 10000000); _ before the array_rand() function, or by shuffling the array first. PHP version was 5.2.5 by the way... ---- Server IP: 212.124.37.9 Probable Submitter: 84.128.229.129 ---- Manual Page -- http://www.php.net/manual/en/function.array-rand.php Edit -- https://master.php.net/note/edit/83100 Del: integrated -- https://master.php.net/note/delete/83100/integrated Del: useless -- https://master.php.net/note/delete/83100/useless Del: bad code -- https://master.php.net/note/delete/83100/bad+code Del: spam -- https://master.php.net/note/delete/83100/spam Del: non-english -- https://master.php.net/note/delete/83100/non-english Del: in docs -- https://master.php.net/note/delete/83100/in+docs Del: other reasons-- https://master.php.net/note/delete/83100 Reject -- https://master.php.net/note/reject/83100 Search -- https://master.php.net/manage/user-notes.php
