How to flush opcache?

Question

According to there documentation i needed to use phpinfo() to check for inconsistencies in my php.ini.

I have put it in the index.php because all other files are not accessable from the web. Or give error's like:

Fatal error: Uncaught Zend_Cache_Exception: cache_dir "/var/www/magento/var/page_cache" is not writable in /var/www/magento/vendor/magento/zendframework1/library/Zend/Cache.php:209 

Is there a command like: magento cache:opcache:reset ?

Answer 1

To clear PHP OPCache you can just restart PHP - systemctl restartphp7.0-fpm (For Ubuntu 16.04)

You can also create an opcache_clear.php file with the contents:

<?php
opcache_reset();
?>

As a side note, to get your phpinfo() to work correctly you need to create the file within the /path/to/magento/pub/ directory to be able to access it via browser, for example:

Create:

/path/to/magento/pub/info.php

Access:

https://example.com/info.php

Answer 2

If you are on development environment Opcache timestamp validation should always be on to avoid refreshing cache when modifying files

opcache.validate_timestamps = On
