[php-src] Issue #8164: PHP8.1.3. opcache bug with monolog/monolog

Issue: https://github.com/php/php-src/issues/8164 Author: R4c00n ### Description Using monolog/monolog on PHP8.1.3 results in some very weird problems with the class vendor/monolog/monolog/src/Monolog/DateTimeImmutable.php not being found. There's also already a bugreport in monolog https://github.com/Seldaek/monolog/issues/1626, but it looks like this is an opcache bug. Our deployment process looks like this: - Upload files to server into release directory - symlink release directory - reset opcache (opcache_reset) After that, we get the PHP message: PHP Fatal error: Uncaught Error: Class "Monolog\DateTimeImmutable" not found in ... error. Resetting opcache a second time fixes the bug and everything is fine until the next deployment. ### PHP Version PHP 8.1.3 ### Operating System Debian
