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.

opcache_reset — Resets the contents of the opcode cache
This function resets the entire opcode cache. After calling opcache_reset(), all scripts will be reloaded and reparsed the next time they are hit.
This function has no parameters.
Returns TRUE if the opcode cache was reset, or FALSE if the opcode
cache is disabled.

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
<?php
opcache_reset();
include 'b.php'
?>
File b.php
<?php
include 'constants.php';
?>
File constants.php
<?php
define('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.
