It should be mentioned that opcache_reset() does not reset cache when executed via cli.
So `php -r "var_dump(opcache_reset());"` outputs "true" but doesn't clean cache. Make file, access it via http - and cache is clean.

For people who have difficulties with constants and opcache_reset().
If you include a file with constant and do an opcache_reset() in the same file, you'll probably have some error like :

"Notice: Constant already defined"

The trick is to call opcache_reset() in an isolated file, then include another file that include the file with constants.

File a.php

File b.php
include 'constants.php';

File constants.php
('MY_CONST', 'abcdef');

With this trick, the opcache will be reset in a.php and when b.php will be included, the constants will not be in cache anymore.
