是否需要OPcache缓存并包含php文件？
I have many classes and php files included to another php files.I use OPcache, but I suspect that it doesn't cache all that included php files. Is that true? If yes, then how to turn on this files caching too?
我有很多类和php文件包含在另一个php文件中。我使用OPcache，但我怀疑它没有' t缓存包含php文件的所有内容。 真的吗？ 如果是，那么如何打开这个文件缓存呢？ p> div>
Generally we use Opcache for caching the complied opcode so that when the same script will run it won’t compile the script again and serves it from cache.
For this you have to enable Opcache in php.ini which will affect your whole application.
opcache.enable = 1;
If you want to achieve this on script to script basis, then no need to enable in php.ini, rather you can set it using ini.set() method.
Now when you want to enable page cache using Opcache which is available from PHP 7.0 onwards, you can do this by enabling this on php.ini or using ini.set() and setting up your cache directory, like below.
opcache.file_cache = “cache_directory”;
