note 32621 added to function.rand

Here is a simple function that will produce a list of UNIQUE random numbers within a range. <? // set some globals $s = array(); $n = 12; // the range you require (this will give 1-12) function set_num() { global $s, $n; $add = "yes"; $ran = rand(1, $n); if(count($s) > 0) { foreach($s as $sh) { if($ran == $sh) { $add = "no"; } } } if($add == "yes") { $s[] = $ran; } else { set_num(); } } // call the function as needed while(count($s) < $n) { set_num(); } // just output a list seperated by whitespace foreach($s as $sh) { echo $sh."&nbsp;"; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32621 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32621&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32621&report=yes
