Feature Request: Option to reset Opcode cache when clearing the cache

[raamdev]

Forked from #342 (comment).

The new PHP 5.5+ Opcache extension allows resetting the Opcode cache via opcache_reset(). ZenCache should have a new option panel called "Opcode Cache" that includes a button to manually reset the Opcode cache, along with an option to disable automatic Opcode cache resetting whenever the ZenCache cache is cleared (the default would be enabled).

This panel can also include a PHP code snippet and reference to the "Process Other Custom PHP Code?" section inside ZenCache → Plugin Options → Clearing the Cache in case the site owner wants more advanced control over this functionality.

@jaswsinc The new "Clear the OPCache Too?" option is located in the new "Manual Cache Clearing" section of the options, which I assume means that it applies only to the "Clear Cache" button, not to any automatic cache clearing routines (there's no corresponding option inside the new "Automatic Cache Clearing" section as I would've expected).

Can you confirm if this was intentional or if you just overlooked it?

[jaswrks]

The OpCache is only cleared in the following circumstances:

• If enabled in the manual section, and you clear the cache manually.
• If enabled in the manual section, and ZenCache clears the entire cache manually and/or automatically. This occurs rarely. Generally speaking, it occurs only when you change the plugin options and/or an upgrade of the software occurs.

I don't think the OpCache should ever be cleared in an automatic way otherwise, because the OpCache really only needs to be cleared whenever filesystem changes occur; i.e., when ZenCache options change and the advanced-cache.php file is rewritten, or when a site owner clears the entire cache and they want to know that everything is being cleared.

@jaswsinc Thanks for the clarification! :-)

Next Pro Release Changelog:

• New Feature! When your server has the PHP OPCache Extension installed, ZenCache can now be configured to also clear the PHP opcode cache whenever you clear the cache manually using the ZenCache "Clear Cache" button. See ZenCache Options → Manual Cache Clearing → Clear the PHP OPCache Too? (note that this option only appears if you have the OPCache Extension installed). Props @jaswsinc. See Issue #489.
