APCu and Symfony2

Question

Since PHP 5.5 broke APC in favor of their own cache, I'm trying to get my Symfony2 project running with APCu instead, and it doesn't like it:

$ php app/console cache:clear --env=prod --no-warmup
PHP Fatal error:  Call to undefined function Doctrine\Common\Cache\apc_fetch() in /home/maf/symfony/vendor/doctrine/cache/lib/Doctrine/Common/Cache/ApcCache.php on line 40

The documentation of APCu is basically non-existent, and the Symfony2 docs are outdated, providing help only for APC.

I regret using PHP these days with all the compatibility-breaking upgrades, but I need to get my project running again. Where do I apply the gaffer tape?

You should make sure that you have APC support emulated, so make sure that you have extension=apcu.so (version >= 4.0) in your php.ini.

I have that, and APCu seems to work (at least the web-frontend tells me so). I still get the above error. – Gurolinick

Make sure that web and cli version of php.ini has it (php -i | grep php.ini, php -m | grep apc). I have no other advice at the moment. – Selfreliance

That was it, thank you. Yes, I had it installed only for the web, not for the CLI, and Symfony2 calls it as CLI on cache clear. Thanks. – Gurolinick
