Known $arrs,

Array (
  
  Array (
    ' Pono ' = ' a ',
    ' No ' = ' 4711 ',
  ),
  
  Array (
    ' Pono ' = ' a ',
    ' No ' = ' 4714 ',
  ),
  
  Array (
    ' Pono ' = ' B ',
    ' No ' = ' 4714 ',
  ),
  
  Array (
    ' Pono ' = ' B ',
    ' No ' = ' 4715 ',
  ),
  
  Array (
    ' Pono ' = ' C ',
    ' No ' = ' 4715 ',
  ),
  
  Array (
    ' Pono ' = ' C ',
    ' No ' = ' 4716 ',
  ),
)

The data are now merged with Pono to:

$tmp =array ();
$data =array ();
$i = 0;
foreach ($arrs as $key = = $arr) {
if (!empty ($tmp) && array_key_exists ($arr [' Pono '], $tmp)) {
        $key = $tmp [$arr [' Pono '];
        $arr _no=explode (', ', $data [$key] [' no ']);
        if (!in_array ($arr [' No '], $arr _no)) $data [$key] [' No '].= ', '. $arr [' no '];
    }else{
        $tmp [$arr [' Pono ']]= $i;
        $data [$i ++]= $arr;
    }
}
Print_r ($data);

Get results:
Array
(
    [0] = = Array
        (
            [Pono] = a
            [No] = 4711,4714
        )

    [1] = = Array
        (
            [Pono] = b
            [No] = 4714,4715
        )

    [2] = = Array
        (
            [Pono] = C
            [No] = 4715,4716
        )
)

Now you want to show only nonadjacent no, such as the item in the example:
[0] = = Array
(
[Pono] = a
[No] = 4711,4714
)

How can I ask?

Print_r ($data);

$result = Array ();

foreach ($data as $val) {
