PHP getcwd() function to be used with include or require in different directories

Question

I need to include a path from a config file in one directory on other scrpits a few directories up or down.

My config file has a function like this:

$execute_path = getcwd() . "/execute.php";

The execute.php file resides in the same directory as the config file wich makes it ok and the output will become:

public-html/config-directory/execute.php

Now if use the same function in a directory that is outside of the original directory, it treats the getcwd() function as if it was in that directory.

For example, if call it from a directory public-html/one/two/three/somefile.php as follow:

<?php 
include(pathto/config.php)
echo $execute_path;
?>

The output becomes publichtml/one/two/three/execute.php rather than staying publichtml/config-directory/execute.php

How can I achieve what I want here? Sorry for the long explanation. Thanks.

Answer 1

Include can be very tricky why i advice is

//config.php

define("SITE_PATH", "public-html/config-directory");


//execute.php

$execute_path =SITE_PATH . "/execute.php";

//run.php
include_once 'config.php';
include_once 'execute.php';

echo $execute_path;
