I have issue with PHP7 and APCu. After installation I got this error:
Fatal error: Call to undefined function Doctrine\Common\Cache\apc_fetch()
APCu is 100% enabled, I see it in the phpinfo();
And when I try apcu_fetch()
it works.
How to use APCu in Symfony 2.8?
You can update Doctrine, at least its doctrine/cache dependency (>= 1.6) APCu now supported :-)
