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.

opcache_compile_file — Compiles and caches a PHP script without executing it
Description
This function compiles a PHP script and adds it to the opcode cache without executing it. This can be used to prime the cache after a Web server restart by pre-caching files that will be included in later requests.
Parameters
-
filename -
The path to the PHP script to be compiled.
Return Values
Returns true if filename was compiled successfully
or false on failure.
Errors/Exceptions
If filename cannot be loaded or compiled, an error of
level E_WARNING is generated. You may use
@ to suppress this
warning.
