Try running this one:

<?php
if(isset($_SERVER["SCRIPT_FILENAME"])){
        $file_name = $_SERVER['SCRIPT_FILENAME'];
        echo "File name: $file_name<br>";
        
        $script = $_SERVER['SCRIPT_NAME'];
        echo "Script: $script<br>";
        
        $document_root = str_replace($script,'',$file_name);
        echo "Document root: $document_root<br>";
        
        $base = basename($document_root);
        echo "Base: $base<br>";
        
        $include = str_replace($base,'include',$document_root);
        echo "Include: $include<br>";
        
        $os = strtolower(PHP_OS);
        echo "OS: $os<br>";

        $lk = ':';
        $org_include = ini_get("include_path");
        if(preg_match('/^win/i',$os))   $lk = ';';
        
        ini_set("include_path",$include.$lk.$org_include);
        echo "Include: ".ini_get("include_path")."<br>";
}

and let me see what it prints
