如何“实际上”配置 PHP APC？
我有 VPS，它运行一个 wp 博客和一个简单的单页网站。我正在尝试使用 APC 来写博客。在安装 APC VPS 之前，它向我发送警报，称 WP index.php 正在吞噬所有内容。现在，安装 APC 后，这些警报已停止。但是当我使用 apc.php 检查结果时，我在系统缓存中没有看到任何文件。
这是 PHP 信息：

我对实际发生的情况感到困惑。我尝试阅读所有可能的来源，但我很困惑。如何只缓存 WP index.php 而不缓存其他内容？这是一个简单的 mod_php 设置，而不是 FastCGI 设置。
I have VPS and it runs a wp blog plus a simple one page site. I am trying to use APC for blog. Before installing APC VPS was sending me alerts saying WP index.php was eating up everything. Now after installing APC these alerts have stopped. But when I check the result using apc.php I don't see any file in system cache.
Here is the PHP Info:
APC Support enabled

I am confused as what is actually going on. I have tried to read all possible sources but I am getting confused. How do I make only cache WP index.php and not others? It's a simple mod_php set up not the FastCGI setup.

就像评论所说，我不知道为什么你不希望缓存所有内容。
然而，根据 文档。您可以在 apc.filters 属性中使用正则表达式来排除除 index.php 文件之外的所有内容。我不是正则表达式专家，但是您的 apc.ini 中类似的内容应该可以工作；
Like the comment says, I have no idea why you wouldn't want everything cached.
However, there seems to be a way to do what you want, according to the docs. You can use a regex in the apc.filters property to exclude everything except the index.php file. I'm not a regex expert, but something along the lines of this in your apc.ini should work;
