       array('id' => 222222,  'name'=>harolds),
       array('id' => 1111111, 'name'=>albert)
   );

so the result I looking is after sort the array as shown below

   $original_array = array( 
      array('id' => 1111111, 'name' => albert),
      array('id' => 222222,  'name' => harolds),
      array('id' => 123456,  'name' => michael)
   );

It is very easy, just do it like this:

$array = array(
    array( 'id' => 123456,  'name' => michael ),
    array( 'id' => 222222,  'name' => harolds ),
    array( 'id' => 1111111, 'name' => albert )
);

usort( $array, function( $a, $b ) {
    return strcmp( $a['name'], $b['name'] );
} );

and you will get what you need! If your php version is 5.2.x or less, do it in this way:

$array = array(
    array( 'id' => 123456,  'name' => michael ),
    array( 'id' => 222222,  'name' => harolds ),
    array( 'id' => 1111111, 'name' => albert )
);

function mysort_func_531994( $a, $b ) {
    return strcmp( $a['name'], $b['name'] );
}

usort( $array, 'mysort_func_531994' );

Read manual for following functions:

1. usort function
2. strcmp function
