设置自定义“根”文件夹以更轻松地包含/需要更深层次的php文件

Question

I was trying to come up with a solution to a problem that I encountered while programming in PHP. I am trying to set a custom "root" folder. I am using MAMP in my computer, so I would like to set as my "root" folder something like this:

$root = "localhost:1234/project/";

I am trying to do this so I can use this in a file, such as file.php that for example is in a deeper lever like

localhost:1234/project/folder1/folder2/file.php

and then inside the file I can maybe require/include another file from the "root" file, such as:

include $root . "/functions.php";

or deeper within a level

include $root . "/folderx/another.php";

Does anybody know how to do this?

I tried dirname(__FILE__); but it doesnt really work.

Thanks!

Answer 1

just remove the slash from your root link
$root = "localhost:1234/project/";
to $root = "localhost:1234/project";
and include your file like this
include $root . "/functions.php";

or
keep your root and require the files without slash
