Bu durumda bana yardımcı olun. Ben bir dizi var, ve ben gibi, yeni bir tane yapmak istiyorum

array[0][id] = 1
array[0][parent_id] = null
array[0][order_id] = 1
array[1][id] = 2
array[1][parent_id] = null
array[1][order_id] = 2
etc.

Benim şu anki dizi bu gibi:

Array
(
[list] => Array // if the (array's name = `list`) the array[#][parent_id] = null
    (
        [0] => 1 // the key of the array (`[0]` in this case) is the array[#][order_id]
        [1] => 2 // the value of the array (`2` in this case) is the array[#][id]
        [2] => 5
    )

[list_2] => Array // else the array[#][parent_id] = the number value after the _
    (
        [0] => 3
        [1] => 4
    )

[list_5] => Array
    (
        [0] => 6
    )
)

A good solution based on Habax's script:

$new = array();
$n=0;
foreach($old as $key=>$item){
    for ($i = 1; $i <= count($item); $i++) {
        if($key=='list')$new[$n]['parent_id']=null;
        else {
          $tmp = explode('_', $key);
          $new[$n]['parent_id']=$tmp[1];
        }
        $new[$n]['order_id']=$i;
        $new[$n]['id']=$item[$i-1];
        $n++;
    }
}
}

Good to arrange nested sortables, like: http://www.b-hind.eu/jquery/
