I have an array, I can print it with
print_r($show_arr);
it gives me this output(html source)
Array
(
[0] => Marvel's Daredevil.S01E01 - Into the Ring.mp4
[1] => Marvel's Daredevil.S01E02 - Cut Man.mp4
[2] => Marvel's Daredevil.S02E05 - Kinbaku.mp4
[3] => Marvel's Daredevil.S02E06 - Regrets Only.mp4
)
how would I go about getting the array to look like this?
Array
(
Season[1] => Array
(
Array(
episode => "01 - Into the Ring",
file => "Marvel's Daredevil.S01E01 - Into the Ring.mp4",
)
Array(
episode => "02 - Cut Man",
file => "Marvel's Daredevil.S01E02 - Cut Man.mp4",
)
)
Season[2] => Array
(
Array(
episode => "05 - Kinbaku",
file => "Marvel's Daredevil.S02E05 - Kinbaku.mp4",
)
Array(
episode => "06 - Regrets Only",
file => "Marvel's Daredevil.S02E06 - Regrets Only.mp4",
)
)

I was bored. Just loop your array and use preg_match() to build the array using the matched groups:
foreach($show_arr as $val) {
preg_match('/[^.]+\.S([\d]+)E([0-9]+[^.]+).*/', $val, $m);
$result['Season'][(int)$m[1]][(int)$m[2]] = array('episode' => $m[2],
'file' => $m[0]);
}
[^.]+ is 1 or more NOT dot . characters
\.S([\d]+) is a dot . then S followed by 1 or more digits (capture as group 1)
E([0-9]+[^.]+) is E followed by 1 or more digits followed by 1 or more NOT dot . characters (capture as group 2)
Additionally, this indexes the subarray by the episode. If you don't want that, remove the [(int)$m[2]] and just use [].
