Magento2 OpCache Manager

Allows the purge/clear/flush of the PHP OpCache via the CLI and Magento2 Backend, _(*1)

Unmaintained

I still see a lot of activity on this repository (usage). I just wanted to note that I'm not maintaining this plugin anymore. This is because I'm not working with Magento at this point. Therefore I have no interest in making new changes/features. Though feel free to make pull-requests and I will process these., _(*2)

Why

Because PHP OpCache is almost the de facto standard in current server/application setups. Most users/developers are usinga simple PHP script to clear the cache or simply ignore this cache. With this extension you can use it in your build/deployment process via the CLI. Also provided is an extension to the Magento2 backend. With a simple click you can purge the cache., _(*3)

About me

I'm a DevOps engineer for a full service digital agency in the Netherlands. When possible I try to create opensource scripts / extentions and tools. If you appriciate my work, please be so kind to donate so I can keep drinking beer., _(*4)

How the CLI works

It is simply not possible to clear the php OpCache via the CLI. I have created a workaround for that. Instead of actually running a static PHP file from the CLI, we do a curl request. Because it is a curl request, your webserver actually will parse this request via the "php cgi". This way we can clear it., _(*6)

The issue we now have is that we do not want robots or "hackers" to be able to clear this cache. Therefor on execution we write a sort of "lock" file. Obviously removing it after clearing. This way "direct access" to this static page is not possible., _(*7)
