Sort a file from the root [duplicate] - php

Question

This question already has answers here:
PHP absolute path to root
(8 answers)
Closed 2 years ago.
I'm using this code
$sort_data = get_sort('data/profiles/name.cms','¦');
The required "Data" folder is in the root of my host, but the php file that calling name.cms is in sub folder : styles/default/pages/left_member.php
and I'm failing to get that data from the name.cms file, any idea how to call the file from the root?

Answer 1

You could make use of the PHP $_SERVER functionality and target the root directory.
Example:
$sort_data = get_sort($_SERVER['DOCUMENT_ROOT'].'/data/profiles/name.cms','¦');
It's important to note that what's actually defined as the root directory is defined in your configuration file.
'DOCUMENT_ROOT' - "The document root directory under which the current
script is executing, as defined in the server's configuration file."

UPDATE AS PER YOUR COMMENT:
Thank you for your help, I already tried it but it's getting whole
xampp directory, so it didn't work.
If you ever take your project "live", the $_SERVER['DOCUMENT_ROOT'] functionality should work. The reason why it doesn't work for you right now, is because you have a "project structure" in your root directory. I.e. localhost/myproject/index.php. What you meant by root is actually the project folder and not the actual root folder.
In that case, you can try 3 different options.
An absolute path without using the PHP reserved variable $_SERVER
to find it.
Example:
$sort_data = get_sort('/data/profiles/name.cms','¦');
Manually manipulate the directory path.
Example:
$sort_data = get_sort('../data/profiles/name.cms','¦');
You can add as many "level up", i.e. ../, as it takes to get to your desired starting point and then locate the folder.
Define your own "root" path variable.
Example:
$my_root = $_SERVER['DOCUMENT_ROOT'].'/myproject';
You can now use $my_root with your path, like so:
$sort_data = get_sort($my_root.'/data/profiles/name.cms','¦');
