installation of apache2 + php82-fpm under macOS Ventura seems to keep php files in cache

A macports' installation of apache2 + php82-fpm under macOS Ventura seems to keep php files in cache, even before installing php82-opcache.

I don't know if this is coming from apache2 or php82-fpm, and I tried to set the cache-control in the header of my script like this without any success :

header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

My production server is under linux and did not present this kind of problem at all.

When I empty the cache of the browser, the script executes correctly, whereas in the opposite case, not.

Edit : fixed this when I realized I had a not default value for php_admin_value[session.save_path] I deleted this setting and everything when better.

Opcode caching and http caching are very different things - only a very trivial analysis would confuse the two.

While your HTTP headers will prevent HTTP caching in most cases they're not correct.

You didn't say why you believed that data was being cached.

Next time check your webserver and PHP logs and what is being sent to your browser using the web developer tools.
