How to get the absolute path to the public_html folder?

$_SERVER['DOCUMENT_ROOT']

returns

/usr/local/apache/htdocs/

is there a way to get

/home/user/public_html/

The problem is that I have to write a script which can be in the public_html folder or a sub-folder of the public_html folder. The script should save uploaded files into a folder inside public_html directory(say images). In other words let us say that my file is test.php and the path to it is

/home/user/public_html/test/test.php.

And there is a folder

/home/user/public_html/images

where files uploaded via test.php have to be saved. I don't know where the test.php file will be run. For example it can be at the path

/home/user/public_html/test/another-dir/test.php

How do I get the path to the images folder without knowing where the test.php file will be?

something I found today, after reading this question and continuing on my googlesurf:

https://docs.joomla.org/How_to_find_your_absolute_path

<?php
$path = getcwd();
echo "This Is Your Absolute Path: ";
echo $path;
?>

works for me

Where is the file that you're running? If it is in your public html folder, you can do echo dirname(__FILE__);

Let's asume that show_images.php is in folder images and the site root is public_html, so:

echo dirname(__DIR__); // prints '/home/public_html/'
echo dirname(__FILE__); // prints '/home/public_html/images'

put anyfile on the directories you wanted to find, in this case, place 'root' at public_html

/home/user/public_html/root <- note that 'root' is not a folder (you can use root.txt if u want)

And use this function

function findThis($get){
    $d = '';
    for($i = 0; $i < 20; $i++){//this will try 20 times recursively on upper folder
        if(file_exists($d.$get)){
            return $d;
        }else{
            $d.="../";
        }
    }
}

and get the value by calling it

$pathToRoot = findThis('root');

And it will return, for example the the dir of php script is

/home/user/public_html/test/another-dir/test.php

so the $pathToRoot will be

$pathToRoot => "../../../"

Is this the one you want??

Whenever you want any sort of configuration information you can use phpinfo().

Out of curiosity, why don't you just use the url for the said folder?

http://www.mysite.com/images

Assuming that the folder never changes location, that would be the easiest way to do it.

This is super old, but I came across it and this worked for me.

<?php
//Get absolute path
$path = getcwd();
//strip the path at your root dir name and everything that follows it
$path = substr($path, 0, strpos($path, "root"));
echo "This Is Your Absolute Path: ";
echo $path; //This will output /home/public_html/
?>

with preg_replace function to find absolute path from __FILE__ you can easily find with anything home user. Here short my code :

$path_image_you_want = preg_replace('#/public_html/([^/]+?)/.*#', '/public_html/$1/images", __FILE__);

You can also use dirname in dirname to get to where you want to be.

Example of usage:

For Joomla, modules will always be installed in /public_html/modules/mod_modulename/

So, from within a file within the module's folder, to get to the Joomla install-root on any server , I could use: $path = dirname(dirname(dirname(__FILE__)));

The same goes for Wordpress, where plugins are always in wp-content/plugins/

Hope this helps someone.
