We recently upgraded our servers to PHP5.5 (I know..) for an older web-app that runs on CI 2.1.1.
We were using the APC library and now the CI_Cache_apc::is_supported() routine is returning false and logging an error message. (disabling some of our manual cache code)
I realise this is some old software we're running, but I wanted to run some things by you.
Am I right in assuming OPCache is a drop-in replacement for APC? In other words: All apc_*() calls are supposed to still work?
I've thought of "patching" is_supported() to check for "Zend OPCache" instead of "apc", but the absence of a new driver for OPCache and/or a similar patch in the latest 2.x and 3.x code-bases makes me hesitant. What is the CI community currently doing to utilise opcode caching?
Thanks in advance,
Alex
