PHP-相对路径"require" [英] PHP - Relative paths "require"
问题描述
我的目录结构如下:
blog -> admin -> index.php
blog.php
db.php
functions.php
我一直在尝试admin/index.php
中的include
(实际上是require
)blog.php
,但是遇到很多错误.我正在学习PHP课程,并且讲师成功完成了同样的事情.
I have been trying to include
(require
, really) blog.php
in the admin/index.php
, but facing lots of errors. I'm following a PHP course, and the instructor does the same thing successfully.
admin/index.php:
admin/index.php:
require "../blog.php";
,这又需要在其目录中再添加两个文件.
which, in turn, requires two more files in its directory.
require "db.php";
require "functions.php";
推荐答案
如果您发现相对包含路径未按预期工作,则快速解决方案是将__DIR__
放在要尝试的路径的前面包括在内.
If you find that relative include paths aren't working as expected, a quick fix is to prepend __DIR__
to the front of the path you're trying to include.
require __DIR__ . "/../blog.php";
它相当干净,您无需修改包含路径或工作目录.
It's reasonably clean, and you don't need to modify the include path or working directory.
