PHP iterating through array returned from a function -

hi have class file contains function retrieve users mysql database. code following :

class userdbase {     public function fetchusers()     {         $db = new mysqli('localhost', 'user', 'pass', 'dbase');          if($db->connect_errno > 0)         {             die('unable connect database [' . $db->connect_error . ']');         }          $sql = "select username `users`";         if(!$result = $db->query($sql))        {            die('there error running query [' . $db->error . ']');        }         while($row = $result->fetch_assoc())        {            $users[] = $row['username'];        }        $result->free();        $db->close();        return array($users);     } } 

the code above returns array following using print_r($dbase->fetchusers()) :

array ( [0] => array     (         [0] => user1         [1] => user2         [2] => user3          )  ) 

i having trouble looping through array main file reference function in class . code using following :

<?php  require("dbase.php");  $dbase = new userdbase();   foreach($dbase->fetchusers() $result)  //this doesn't work  {     print "$result";   } ?> 

can more versed in php point me out correct way ? in advance !

when build array of users[] here:

while($row = $result->fetch_assoc()) {     $users[] = $row['username']; } 

$users array, when return it, wrapping in array() means returning array of arrays not process.

solution return $users.
