PHP中的require_once [英] require_once in php

问题描述

我有一个php文件，该文件具有require_once语句(?)，然后将该文件包含在其他2个php文件中，一个php文件位于子目录中，因此布局如下("file1"和"file2"包括文件"included"，其中"require_onces"是"required")#

I have a php file which has a require_once Statement (?) this file is then in included in 2 other php files, one php file is in a sub directory so the layout is like this ("file1" and "file2" include the file "included" which require_onces the "required")#

 L--subfolder1
 | L--file1
 L--subfolder2
 | L--required
 L--file2
 L--included

如何从"included"文件中引用"required"文件，以便它在file1和file2中都可以使用?

How can I reference the "required" file from the "included" file so that it will work from both file1 and file2?

推荐答案

始终使用绝对路径

$_SERVER['DOCUMENT_ROOT']."/included";

或

$_SERVER['DOCUMENT_ROOT']."/subfolder2/required";

可以在任何地方工作
