如何使DOCUMENT_ROOT在本地主机和Web主机上都能工作? [英] How to get DOCUMENT_ROOT to work on both localhost and web host?

问题描述

我有一个WordPress插件，我想在localhost上以及在不做任何修改的情况下进行部署，但是我似乎无法使用一条语句来设置目录的位置.

I have a WordPress plugin that I would like to work on localhost as well as in deployment without modification, but I can't seem to set the location for a directory using one statement.

我想这样做:

$feed->set_cache_location($_SERVER['DOCUMENT_ROOT'] . '/wp-content/cache');

虽然可以在网络主机上运行.在本地主机上，它将产生此错误:

While that works on the web host. On localhost it produces this error:

C:/xampp/htdocs/wp-content/cache/a547b8792c3144c98549be23ef1465e7.spc is not writeable

在localhost上，我需要将其设置为此才能起作用:

On localhost, I need to set it to this to get it work:

$feed->set_cache_location($_SERVER['DOCUMENT_ROOT'] . '/mysite/wp-content/cache');

肯定一定有一些东西既可以在localhost上运行，也可以在网络主机上运行！

Surely there must be something that works both on localhost and on a web host!

谢谢.
