You could try this, it works fine : <?php $connection = mysql_connect ($host, $login, $password); mysql_select_db ($DataBase, $connection) ; $c = 5 ; // Whatever.. protected function randomselection($c, $connection) { $data = getdata($connection) ; // Get your datas somewhere you like to $totalcount = count($data) ; $j = array() ; if ($c > $totalcount) { $newdata = $data ; } // if not enough datas rows in $data else { for($i = 0; $i <= $c; $i++) { $exists = 1 ; for($exists > 0; $exists++;) { $test = mt_rand(1,$totalcount) ; // depends on where you want to start - can also use rand() if(!in_array( $test , $j )) { $j[$i] = $test ; $exists = 0 ; } } $newdata[$i] = $data[$j[$i]] ; } } return $newdata ; } ?> ---- Server IP: 194.246.101.61 Probable Submitter: 87.90.26.94 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/70844 Del: integrated -- https://master.php.net/note/delete/70844/integrated Del: useless -- https://master.php.net/note/delete/70844/useless Del: bad code -- https://master.php.net/note/delete/70844/bad+code Del: spam -- https://master.php.net/note/delete/70844/spam Del: non-english -- https://master.php.net/note/delete/70844/non-english Del: in docs -- https://master.php.net/note/delete/70844/in+docs Del: other reasons-- https://master.php.net/note/delete/70844 Reject -- https://master.php.net/note/reject/70844 Search -- https://master.php.net/manage/user-notes.php
