[BUG] Calling flush() on \Phalcon\Cache\Backend\Apcu fails

[ilogs-sepa]

Expected and Actual Behavior

Describe what you are trying to achieve and what goes wrong.

I want to clear/purge the complete APCU cache by calling the flush method from the Backend class.
At the moment this just yields the following exception text:

Call to undefined function apc_delete()

The exepcted behaviour is to silently purge what is there to purge.

Seems to be a simple bug.

Details

• Phalcon version: 3.2.0
• PHP Version: 7.1.5

There is two extensions:

• APC
• APCU

These extensions provides their own functions:

• apc_
• apcu_

To use APC functions like apc_delete (note, not apcu_delete) with APCU extensions you have to install and enable acpu_bc extension. https://pecl.php.net/package/apcu_bc

Fixed in the 3.2.x branch. Feel free to open new issue if the problem appears again. Thank you for contributing.
