Here is a reproducer using file cache, though the same would also work through SHM: file1.php: <?php return function() {}; file2.php: <?php $file = 'file1.php'; var_dump(include $file); touch($file); var_dump(include $file); Then run file1.php first and file2.php second under -d opcache.file_cache_only=1.
