You can use array_slice

$res = [];
foreach($arr as $key => $value){

  $res[$key][1] = array_slice($value, 0, 2, true);
  $res[$key][2] = array_slice($value,2, null, true);    
}

var_dump($res);

output:

Array
(
    [1] => Array
        (
            [1] => Array
                (
                    [9] => 6
                    [11] => 6
                )
            [2] => Array
                (
                    [12] => 6
                    [13] => 6
                    [14] => 12
                )
        )
    [2] => Array
        (
            [1] => Array
                (
                    [4] => 8
                    [8] => 8
                )
            [2] => Array
                (
                    [13] => 13
                )
        )
)

Only PHP > 5.2.4 : changelog says: The default value of the length parameter was changed to NULL. A NULL length now tells the function to use the length of array. Prior to this version, a NULL length was taken to mean a zero length (nothing will be returned).

Use array_chunk and array_slice.

$res = [];
foreach($arr as $k => $v){

  $lastdata = array_slice($v, 2,NULL,true);
  $firstdata = array_chunk($v,2,true);

  $res[$k]['1'] = $firstdata[0];
  $res[$k]['2'] = $lastdata;

}

echo '<pre>'; print_r($res);

output:-

Array
(
    [1] => Array
        (
            [1] => Array
                (
                    [9] => 6
                    [11] => 6
                )

            [2] => Array
                (
                    [12] => 6
                    [13] => 6
                    [14] => 12
                )

        )

    [2] => Array
        (
            [1] => Array
                (
                    [4] => 8
                    [8] => 8
                )

            [2] => Array
                (
                    [13] => 13
                )

        )

)

Hope it will help you :)

    $a=array('1'=>array('9'=>'6','11'=>'6','12'=>'6','13'=>'6','14'=>'12'),'2'=>array('4'=>'8','8'=>'8','13'=>'13'));
    $res = array();
    foreach($a as $k => $v){

      $lastdata = array_slice($v, 2);
      $firstdata = array_chunk($v,2,true);

      $res[$k]['1'] = $firstdata[0];
      $res[$k]['2'] = $lastdata;

    }

echo '<pre>'; print_r($res);

You can try this - 

$new= array_map(function($v) {
    $temp = array_chunk($v, 2); // break in chunks of 2
    $final[]= array_shift($temp); // Take the first chunk out
    $second= array();
    foreach($temp as $t) {
        $second = array_merge($second, $t); // merge the rest chunks
    }
    if(!empty($second)) {
        $final[]= $second;
    }
    return $final;
}, $array);

Fiddle
