ABSPATH还是__FILE__? [英] ABSPATH or __FILE__?

问题描述

有人可以告诉我这两种方法是否都比其他方法有优势，为什么?

Can someone tell me if either of these two methods has an advantage over the other and why?

$mydir = ABSPATH.'/wp-content/themes/mytheme/images';

$mydir = dirname(__FILE__).'/images';

它们既可以用于获取"mytheme"图像目录的绝对路径，也可以用于将wordpress安装在根目录还是根目录之外的子目录中的结构.在这两种情况下，都可以从"mytheme"文件夹下的functions.php文件中调用它们.

They can both be used to obtain and absolute path to the images directory of "mytheme" regardless of structure of whether wordpress is installed on the root directory or in a subdirectory off the root. In both cases, they are being called from the functions.php file which is located under the "mytheme" folder.

推荐答案

我个人更喜欢dirname()，因为它始终可以确保为我提供正确的结果，而ABSPATH方法依赖于固定的主题路径和主题名称，都可以改变.

I would personally prefer dirname() as it is always guaranteed to give me the correct result, while the ABSPATH method relies on a fixed theme path and theme name that can both change.

顺便说一句，您可以使用__DIR__代替dirname(__FILE__).

By the way, you can use __DIR__ instead of dirname(__FILE__).
