Symfony 3/APCu + PHP7

Question

我再次遇到APCu和PHP7的问题.这是我的conf.

framework:
    validation:
        cache: validator.mapping.cache.doctrine.apc
    serializer:
        cache: serializer.mapping.cache.apc

doctrine:
    orm:
        metadata_cache_driver: apcu
        result_cache_driver: apcu
        query_cache_driver: apcu

网站工作正常,但是当我发送表单时,我总是收到此错误:

[2016-06-29 09:17:12] request.CRITICAL:未捕获PHP异常Symfony\Component\Debug\Exception\UndefinedFunctionException:"尝试从命名空间"Doctrine\Common\Cache"调用函数"apc_fetch"." at ROUTE_TO_PROJECT/vendor/doctrine/cache/lib/Doctrine/Common/Cache/ApcCache.php第41行{"exception":"[object](Symfony\Component\Debug\Exception\UndefinedFunctionException(code:0):试图调用来自命名空间\"Doctrine\Common\Cache \"的函数\"apc_fetch \".在ROUTE_TO_PROJECT/vendor/doctrine/cache/lib/Doctrine/Common/Cache/ApcCache.php:41)"} []

这是我的作曲家:

为什么Symfony调用apc_fetch而不是apcu_fatch？

Answer 1

在以前的版本中APCu,APC模块和功能是作为库的一部分提供的.

在最新的(PHP 7)版本中APCu,向后兼容APC是一个单独的扩展.
