Summary: Followup to rP3f5f18a8d6ee7e67e45842b2e63b6485283ee42a. No clue why I missed all this stuff at that time. APC saw its last release in 2012. It has been discontinued as PHP 5.5+ includes OpCache. It has been superseded by APCu for object caching. See https://pecl.php.net/package-info.php?package=APC Phorge requires PHP 7.2. Thus remove remaining calls to APC functions. The PHP documentation does not even include APC functions anymore, you need to visit web archives, for example: * https://web.archive.org/web/20200518114542/https://www.php.net/manual/en/function.apc-cache-info.php * https://web.archive.org/web/20200518114557/https://www.php.net/manual/en/function.apc-clear-cache.php * https://web.archive.org/web/20200518114721/https://www.php.net/manual/en/function.apc-sma-info.php Closes T16116 Test Plan: Same as rP3f5f18a8d6ee7e67e45842b2e63b6485283ee42a, I assume.
