- * Detect if this request has had its POST data stripped by exceeding the

- * PHP has a setting called 'post_max_size'. If a POST request arrives with
- * a body larger than the limit, PHP doesn't generate $_POST but processes
- * the request anyway, and provides no formal way to detect that this
- * happened.
- *
- * We can still read the entire body out of `php://input`. However according
- * to the documentation the stream isn't available for "multipart/form-data"
- * (on nginx + php-fpm it appears that it is available, though, at least) so
- * any attempt to generate $_POST would be fragile.
