This is the type of thing that usort() is used for:

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

function alphasort($a, $b) {
    if ($a['name'] == $b['name']) {
        return 0;
    }
    return ($a['name'] < $b['name']) ? -1 : 1;
}

usort ($original_array,'alphasort');
var_dump($original_array);

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:

usort function
strcmp function

You can try following way.

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

foreach ($original_array as $key => $row) {
    $volume[$key]  = $row['id'];
    $edition[$key] = $row['name'];
}



array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $original_array);

Prasad.
