As I recall, Zend Opcache has various settings to control if and when it
will recompile the PHP scripts in caches. Depending on what settings you
choose, in a FastCGI environment it can periodically check to see if a
script has been updated and update the cache if need be - or, if you
choose, never revalidate the cache, in which case you'd need to reload or
restart php-fpm after changing code.

Also, WordPress has code that tries to clear opcache. [1, 2]
