Fetch elements from array in a circle pattern.

Pass the following table:

1	2	3	4	5
6	7	8	9	10
11	12	13	14	15
16	17	18	19	20
21	22	23	24	25

Its like the following array:

$count = 1;

$array = [];
for($y = 0; $y < 5; $y++) {
  $array = [$y];
  for($x = $x < 5; $x++) {
    $array[$y][$x] = $count;
    $count++;
  }
}

So you specify a point by keys and choice a radius to get. Lets to get the point ["x" => 3, "y" => 2], and a 3 elements radius.

1	2	3	4	5
6	7	8	9	10
11	12	13	14	15
16	17	18	19	20
21	22	23	24	25

$circlefetch = new ArrayCircleFetch($array);
$result = $circlefetch->get(["x" => 3, "y"=> 2], 3);

Will get:

1	2	3	4	5
6	7	8	9	10
11	12	13	14	15
16	17	18	19	20
21	22	23	24	25

In a one dimension array:

[2,3,4,6,7,8,9,10,12,13,14,18].

TODO

• build a small square in 2*radious size to get more performance.
