Previous Comments: ------------------------------------------------------------------------ [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? ------------------------------------------------------------------------ [2012-05-06 11:42:59] bsnxff at gmail dot com Description: ------------ run test_array_rand.php Test script: --------------- <?php $array = array_fill(0, 1000, 'a'); echo rand(0 , 10000); function ref(&$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() // Hi refresh it 3 - 10 times // you will see // random number no longer random // 1 return 10 // 2 return 4453 // 3 return 1251 // 4 return 10 // 5 return 4453 // 6 return 1251 // ... ?> Expected result: ---------------- make rand(0, 10000) random Actual result: -------------- rand(0, 10000) no longer random ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61963&edit=1
