PHP Get Current URL Full Path

In PHP Get Current URL, I have explained how get current page URL with parameters in PHP. To Get Current URL of the Page, we can use $_SERVER environment variables.
Below is the list of useful environment variables for getting current Page URL.

$_SERVER['HTTP_HOST'] => Host name from the current request.
$_SERVER['HTTP'] =>  Set to a non-empty value if the protocol is HTTP
$_SERVER['HTTPS'] =>  Set to a non-empty value if the protocol is HTTPS
$_SERVER["SERVER_PORT"] => Server port. Default is: 80
$_SERVER['REQUEST_URI'] =>  The URI to access this page; 
For example, '/index.php'.

1). We can get protocol schema

$schema = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";

2). If the server is running on standard port(80,443), full URL path becomes:

$schema.$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
//EX: http://www.hayageek.com/test.php

3). If the server is running on non standard port, full URL Becomes

$schema.$_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];

//EX: http://www.hayageek.com:8080/test.php

Note: In PHP, We can not read URL path after hash(#) tag. Because browser does not send the hash data to server. You can get #tag data only with JavaScript.

Combing all, below is the function for getting current web page URL in PHP

function getCurrentURL()
{
	$currentURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
	$currentURL .= $_SERVER["SERVER_NAME"];

	if($_SERVER["SERVER_PORT"] != "80" && $_SERVER["SERVER_PORT"] != "443")
	{
    	$currentURL .= ":".$_SERVER["SERVER_PORT"];
	} 

        $currentURL .= $_SERVER["REQUEST_URI"];
	return $currentURL;
}

Usage:

echo getCurrentURL();
