I've tried running it from the command line with the same result. I've done a little more testing, and it seems that rand() seems to work just fine, so that should more or less exclude the possibility of a bug in srand(). I've also done a full reinstall (just to make sure) without any luck. ------------------------------------------------------------------------ [2002-05-01 03:08:01] derick@php.net I could not reproduce this, are you sure the browser is not caching your page? Derick ------------------------------------------------------------------------ [2002-04-30 08:14:09] joseppo@hotmail.com As of PHP 4.2.0, shuffle() doesn't seem to work for me. The following code always produce the same output: function make_seed() { // Taken directly from the manual list($usec, $sec) = explode(' ', microtime()); return (float) $sec + ((float) $usec * 100000); } srand(make_seed()); $arr = range(1, 10); shuffle($arr); print_r($arr); Further testing shows that I get the same output if I uncomment the srand(), if that's any help. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16926&edit=1
