Quick Magento File Cache Backend Cleaner

This script is intended as a tool to save time during development.
It allows cleaning the Magento file cache backend more quickly than the native bin/magento cache:clean CLI command.

The problem with bin/magento is that it's very slow bootstrap. Cleaning the cache tags with the file system backend takes only a fraction of the bootstrapping time.

This script was inspired by Timon de Groot's blog post https://blog.timpack.org/speed-up-magento-development
He has the brilliant idea to use a file watcher in PHPStorm to call redis-cli to clear the complete cache whenever a XML file is modified.

The motivation for this script is to be able to use a more granular cache cleaning approach based on cache tags via a file watcher,
as rebuilding the cache takes so much longer than cleaning it, regardless of the cleaning strategy (even with bin/magento)

So this current script is only the first step.
The next step is to build a file watcher that will call this script with the appropriate tags.

There is only so much that can be done, but at least two of the most common cases can be covered:

• layout xml file change -> layout and full_page cache
• any other xml file change -> config cache

Maybe something can also be done in regards to changes in routes.xml, webapi.xml and maybe even new controller action classes (which require the config cache to be cleaned).

Of course it also can be used manually.

If this goes somewhere I'll make a composer package out of it that can be added as a require-dev dependency to projects.

For the record, on my 2012 MBP running bin/magento cache:clean takes about 1 second, the above script takes about 0.06 seconds.

In case someone stumbles over this gist, check out https://github.com/mage2tv/magento-cache-clean which is an evolved version with a file watcher.
