How to get the base url in php

Suppose you have to retrieve the URL of the application in PHP i.e http://example.com
Using this piece of code

//output : example.com
$DOMAIN = $_SERVER['SERVER_NAME']; 
// output: http:// 
$protocol = stripos($_SERVER['SERVER_PROTOCOL'],'https') === true ? 'https://' : 'http://'; 
// output : http://example.com
$main_url = $protocol.$DOMAIN;

When you are running the application in the subfolder / subdomain in the main website.I.e http://example.com/myproject/
In this case you want to retrieve the base url of the application not the main site url.

Use this simple function to get the base url of your application.

 
function getBaseUrl() 
{
    // output: /myproject/index.php
    $currentPath = $_SERVER['PHP_SELF']; 

    // output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index ) 
    $pathInfo = pathinfo($currentPath); 

    // output: example.com
    $hostName = $_SERVER['HTTP_HOST']; 

    // output: http://
    $protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https://'?'https://':'http://';

    // return: http://example.com/myproject/
    return $protocol.$hostName.$pathInfo['dirname']."/";
}

$base_url = getBaseUrl();
