Another alternative to shuffle: function rand_cmp( $a, $b ) { $num = (rand( 0, 2 )) - 1; return round( $num ); } usort( $somearray, "rand_cmp"); This returned faster and more reliable results for me on a Windows box than shuffle. It also provides a good foundation to expand into "weighted" randomization as needed. Since it uses usort, it may still be a problem on Solaris. Feel free to post an update in that regard. -- http://www.php.net/manual/en/function.shuffle.php http://master.php.net/manage/user-notes.php?action=edit+29129 http://master.php.net/manage/user-notes.php?action=delete+29129 http://master.php.net/manage/user-notes.php?action=reject+29129
