php - จัดเรียง array แบบ 2 มิติหน่อยครับ ทำแบบมิติเดียวได้แล้วครับ

<?php 
$multiArray = Array( 
    Array("id" => 1, "name" => "Defg"), 
    Array("id" => 2, "name" => "Abcd"), 
    Array("id" => 3, "name" => "Bcde"), 
    Array("id" => 4, "name" => "Cdef")); 
$tmp = Array(); 
foreach($multiArray as &$ma) 
    $tmp[] = &$ma["name"]; 
array_multisort($tmp, $multiArray); 
foreach($multiArray as &$ma) 
    echo $ma["name"]."<br/>"; 
                
/* Outputs 
    Abcd 
    Bcde 
    Cdef 
    Defg 
*/ 
?> 

<?
// string
$Family = array ( "Somchay"  => array ( "Father" => "Pichai","Mom" => "Suvimon"),
                  "Nipon" => array ( "Father" => "Pichai","Mom" => "Suvimon"));
