note 106623 added to function.rand

Here is another function that will return an array of unique random numbers. It may be more efficient than the one below when dealing with a large range. <?php function generate_random_numbers($min,$max, $total){ $x = 0; $out = array(); while($x < $total){ $num = rand($min, $max); if($x){ while(in_array($num, $out)){ $num = rand($min, $max); } } $out[$x] = $num; $x++; } return $out; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 71.195.64.60 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/106623 Del: integrated -- https://master.php.net/note/delete/106623/integrated Del: useless -- https://master.php.net/note/delete/106623/useless Del: bad code -- https://master.php.net/note/delete/106623/bad+code Del: spam -- https://master.php.net/note/delete/106623/spam Del: non-english -- https://master.php.net/note/delete/106623/non-english Del: in docs -- https://master.php.net/note/delete/106623/in+docs Del: other reasons-- https://master.php.net/note/delete/106623 Reject -- https://master.php.net/note/reject/106623 Search -- https://master.php.net/manage/user-notes.php
