hey, guys.
I make a bet, you havent check opcache status before. So reset code as follow if you can:
    $opcache_status = opcache_get_status();
    if (isset($opcache_status["opcache_enabled"]) &&
!$opcache_status["opcache_enabled"]) {
        echo "opcache empty, so skip it";
        exit(0);
    }

    // now you can reset opcache


have a fun to you:)

Description:
------------
There seems to be a race condition under which opcache_reset() returns false, although the opcache
extension is loaded.

Make sure the opcache extension is loaded. Create the Test script on a webserver and call it a
couple of times. In most cases it will return true, but sometimes it returns false.

Please note I reproduced this on a server where requests are actually coming in.

This also happens during our deployment, where we call opcache_reset() only once. It also happened
among projects with different codebases (Laravel, ZF, self coded), so it doesn't seem to be
related to our code. 

Test script:
---------------
<?php echo opcache_reset();
