Okay, so, let's say you have some data like this:

$things = [
  0 => [ 'id' => 123, 'title' => '123 Title', 'content' => '123 Content' ],
  1 => [ 'id' => 456, 'title' => '456 Title', 'content' => '456 Content' ],
  2 => [ 'id' => 789, 'title' => '789 Title', 'content' => '789 Content' ],
];

Use this just like `add_filter()`, and then run something that calls the filter (like
`new WP_Query`, maybe).

call `remove_filter` again after your call.
