PHP-使用require_once/include/require，路径相对于什么? [英] PHP - with require_once/include/require, the path is relative to what?

问题描述

在"index.php"上时，我会执行require_once("/all_fns.php").

"all_fns.php"本身要求文件具有相对于all_fns.php的路径(本身).

"all_fns.php" itself requires files with paths relative to all_fns.php (itself).

我的问题是，我应该在all_fns上相对于all_fns.php或index.php的路径上写路径吗?

My question is, should I write the paths on all_fns relative to all_fns.php or to index.php?

这一切都让我感到困惑，并想弄清楚它.

This is all very confusing to me and wanted to get it straight.

推荐答案

它们被视为相对于index.php的.

如果您需要引用与包含相关的文件，请使用

If you need to reference a file relative to the include, use

__DIR__."/relative/file.php";
