Description:
------------
I've updated a script but PHP doesn't appear to detect this. Could it be a caching issue?
The 'update' is a bit weird, I've replaced phpMyAdmin by Adminer. 
/var/www/html/pma used to be a symlink to /srv/pma
Now it's a directory containing adminer's index.php: https://github.com/vrana/adminer/releases/download/v4.6.3/adminer-4.6.3-mysql-en.php

Web server is nginx.
The request is for /var/www/html/pma/index.php.

> getcwd("/usr/share/phpmyadmin", 4095)   = 22

Not sure why it does this.

> chdir("/var/www/html/pma")              = 0

OK

> stat("/srv/pma/libraries/common.inc.php", {st_mode=S_IFREG|0644, st_size=13837, ...}) = 0

Hmm, that's from the OLD script.



Test script:
---------------
https://github.com/vrana/adminer/releases/download/v4.6.3/adminer-4.6.3-mysql-en.php


Expected result:
----------------
200 OK

Actual result:
--------------

check your opcache settings, when validation is disabled you need to reload php

opcache.use_cwd = 1
opcache.validate_timestamps = 1
opcache.revalidate_freq = 5

This might be a duplicate of bug #74268.  Anyhow, does it still
happen with any of the actively supported PHP versions[1]?
