Afaik, PHP can have opcode caching enabled or disabled.

True. I see a "Zend OPcache" section in my phpinfo().

It says:

    Cache hits   4746528
    Cache misses   38875

Both values go up every time I execute phpinfo().

I wonder why. Shouldn't "Cache misses" only go up when a source file is changed?

AFAIK, before PHP even accesses opcache for bytecode, it checks the file's metadata (last modified, most likely). So an updated file might never trigger a cache hit or miss.

If it does not access the opcache, against what is it checking the last modified date?
