<?php public function renderLayout3x3($data=array()){
    $output = "<ul>";

    foreach ($data as $key => $value) {
        if($value['posisi'] == '1'){
            $output .= "<li><ul>
                                <li>POS:".$value['posisi']."</li>
                                <li>HOSTNAME:".$value['hostname']."</li>
                        </ul></li>";
        }
        if($value['posisi'] == '2'){
            $output .= "<li><ul>
                                <li>POS:".$value['posisi']."</li>
                                <li>HOSTNAME:".$value['hostname']."</li>
                        </ul></li>";
        }
        if($value['posisi'] == '3'){
            $output .= "<li><ul>
                                <li>POS:".$value['posisi']."</li>
                                <li>HOSTNAME:".$value['hostname']."</li>
                        </ul></li>";
        }

        //for debug..
        print json_encode($value['posisi']);
        /*
        Output : "2","1","3","4","5","6","7","8","9"
        Why : 2 - 1 - 3 - etc, not 1 - 2 - 3 - etc 
        */
    }
    $output .= "</ul>";
    return $output;

$render = renderLayout3x3($json_data);
print $render; ?>

output always :

Output : "2","1","3","4","5","6","7","8","9" Why : 2 - 1 - 3 - etc, not 1 - 2 - 3 - etc

this is other output :
