Be aware that opcache will only compile and cache files older than the script execution start.

For instance, if you use a script to generate cache files (e.g. you don't have access to shmop and rely on opcache for in-memory data caching instead), opcache_compile_file will not include the generated file in the cache, because its modification time is after the script start.

The workaround is to use touch() to set a date before the script execution date, then opcache will compile and cache the generated file.
