Opcache settings for the Zend Engine are notoriously undocumented. So we try to choose good defaults for QualityBox. The book 'Scaling PHP' has some good explanations<ref>https://www.scalingphpbook.com/blog/2014/02/14/best-zend-opcache-settings.html</ref>
However, if you ever need to reset a few, you could use sed, with a quick <code>apachectl -k graceful</code> to reload apache.
<source lang="bash">
# as root
myini=/etc/php.ini
sed -i s/opcache.interned_strings_buffer=4/opcache.interned_strings_buffer=16/ $myini
sed -i s/opcache.revalidate_freq=30/opcache.revalidate_freq=0/ $myini
sed -i s/opcache.validate_timestamps=1/opcache.validate_timestamps=0/ $myini
sed -i s/\;opcache.fast_shutdown=0/opcache.fast_shutdown=1/ $myini
apachectl -k graceful
</source>
