This is the url of my script: localhost/do/index.php

I want a variable or a function that returns localhost/do (something like $_SERVER['SERVER_NAME'].'/do')

My Suggestion:

const DELIMITER_URL = '/';
$urlTop = explode(DELIMITER_URL, trim(input_filter(INPUT_SERVER,'REQUEST_URI'), DELIMITER_URL))[0]

Test:

const DELIMITER_URL = '/';
$testURL = "/top-dir";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

$testURL = "/top-dir/";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

$testURL = "/top-dir/test";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

$testURL = "/top-dir/test/";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

$testURL = "/top-dir/test/this.html";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

$testURL = "/top-dir/test.html";
var_dump(explode(DELIMITER_URL, trim($testURL, DELIMITER_URL))[0]);

Test Output:

string(7) "top-dir"
string(7) "top-dir"
string(7) "top-dir"
string(7) "top-dir"
string(7) "top-dir"
string(7) "top-dir"

My Contribution
Tested and worked

/**
* Get Directory URL
*/
function get_directory_url($file = null) {
    $protocolizedURL = $_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    $trailingslashURL= preg_replace('/[^\/]+\.php(\?.*)?$/i', '', $protocolizedURL);
    return $trailingslashURL.str_replace($_SERVER['DOCUMENT_ROOT'], '', $file);
}

USAGE
Example 1:
<?php echo get_directory_ur('images/monkey.png'); ?>
This will return http://localhost/go/images/monkey.png

Example 2:
<?php echo get_directory_ur(); ?>
This will return http://localhost/go/
