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 ;
			}
?>
