将数组转换为二维数组并删除前11个条目

Question

I have been trying to figure this out until my brain imploded. Im trying to sort an array.

The first 11 entries has to be removed, then the next 7 entries has to be placed in an new array and then the next 7 entries and so on. Until there is no more entries.

Short example:

Turn this:

Array (
     [0] => 0
     [1] => 1
     [2] => 2
     [3] => 3
     [4] => 4
     [5] => 5
     [6] => 6
     [7] => 7
     [8] => 8
     [9] => 9
     [10] => 10
     [11] => 11
     [12] => 12
     [13] => 13
     [14] => 14
     [15] => 15
     [16] => 16
     [17] => 17
     [18] => 18
)

Into this:

Array (
     [0] => Array (
               [0] => 11
               [1] => 12
               [2] => 13
               [3] => 14
               [4] => 15
               [5] => 16
               [6] => 17
            )
)

Something like this should do the trick:

$orig = array(...);

$i = 11; // start at offset 11
$remove = 7; // take off 7 at a time

$new = array();
while($i <= count($orig)) {
   $new[] = array_slice($orig, $i, $remove);
   $i += $remove;
}

$new will have your new multi-dimensionalized array
