Answer 1

Array filter was a good try, did you do it like this :

$channel = 'trance';
$show_data = array_filter($show_data, function($data) use ($channel) {
    return $data['channel'] == $channel;
});

Answer 2

You can do it by array_filter() using any key has value.

For e.g Channel => trance then it will return matched arrays.

$value = 'trance';
$key = 'channel';

$show_data = array_filter($array, function($itrate) use ($value,$key) {
    return $itrate[$key] == $value;
});
