I have a combination of Nginx and PHP-FPM, and I want to set the max execution time on the PHP level to be the same as on Nginx. So I add max_execution_time=30 but it does not work.
If I create an endpoint with the logic like this:

     foreach (range(1, 50) as $i) {
            sleep(1);
            if ($i > 40) {
                $this->logger->error('Processing request', ['i' => $i]);
                continue;
            }

            if ($i > 20) {
                $this->logger->warning('Processing request', ['i' => $i]);
                continue;
            }

            $this->logger->info('Processing request', ['i' => $i]);
        }

        $this->logger->info('Request processed');

and running that script after 30 seconds I see 504 from Nginx, but PHP still processing the request and writing logs. What I’m doing wrong?
