APC is (more or less) a deprecated package (the last release, 3.1.14, was unstableand had to be rolled back). It has been replaced by the core package opcache.
APC（或多或少）是一个不推荐使用的软件包（最后一个版本 3.1.14不稳定，必须回滚）。它已被核心包 opcache 取代。
I'm not sure about Debian flavors (all my searches return the PECL library while opcache is native to 5.6) but in CentOS you have to install the php-opcachepackage, which contains the opcahce.so file.
我不确定 Debian 的风格（我的所有搜索都返回 PECL 库，而 opcache 是 5.6 原生的）但在 CentOS 中，您必须安装php-opcache包含 opcahce.so 文件的软件包。

As mentioned by others on this question, on PHP 5.6, you probably don't want the full APC package. Instead, you almost certainly just want the user-data caching portion, APCu.
正如其他人在这个问题上提到的那样，在 PHP 5.6 上，您可能不想要完整的 APC 包。相反，您几乎可以肯定只想要用户数据缓存部分 APCu。
If you're using PECL, you need to specify the correct version of APCu to use which appears to be 4.0.11:
如果您使用的是 PECL，则需要指定要使用的正确版本的 APCu，它似乎是 4.0.11：
pecl install apcu-4.0.11
(Worked for me on CentOS 6, EasyApache 3, Apache 2.2, PHP 5.6.39. )
（在 CentOS 6、EasyApache 3、Apache 2.2、PHP 5.6.39 上为我工作。）
