Previous Comments: ------------------------------------------------------------------------ [2012-05-11 07:30:31] rasmus@php.net Yes, I tested your case. On my Linux box I get random values. Like I said, it depends on your operating system's pseudo-random generator. ------------------------------------------------------------------------ [2012-05-11 07:27:30] bsnxff at gmail dot com Have you tested this case? rand() will return fixed values not random values. but mt_rand() works this is not what user expected. <?php $array = array_fill(0, 1000, 'a'); function ref(&$data = false) { global $array; $data = &$array; $a = randArray($data); } function randArray($data) { global $array; //may be wrong here $array[] = array_rand($array, 1); return $data[rand(0, sizeof($data) - 1)]; } $i = 1000; while ($i--) ref(); //echo mt_rand(0 , 10000); //echo "\n"; echo $array[rand(0, sizeof($array) - 1)]; ?> ------------------------------------------------------------------------ [2012-05-11 07:17:21] bsnxff at gmail dot com Yes mt_rand works :S Me bad luck. ------------------------------------------------------------------------ [2012-05-11 04:42:19] rasmus@php.net because it makes no sense and on operating systems with a decent random number generator built in there is no bug. Windows XP is not such an operating system. You can try mt_rand() and see if you have more luck with that. rand() gives you the OS-native pseudo-random generator. ------------------------------------------------------------------------ [2012-05-11 04:04:42] bsnxff at gmail dot com No one going to take this bug? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
