Getting Current Page URL:

We are going to use PHP built-in functions to get current page URL in PHP.

• $_SERVER['HTTP_HOST']
• $_SERVER['REQUEST_URI']

Let us discuss each one seperately

Note: I was checking the code in the following URL

$_SERVER['HTTP_HOST'] function in PHP

This is a simple php function which displays the host name of current page.

Example:

<?php
$hostName=$_SERVER['HTTP_HOST'];
echo $hostName;
?>

Ouput:

$_SERVER['REQUEST_URI'] function in PHP

The above function displays the remaining URL of the current page other than the host name.

Example:

<?php
$pathName=$_SERVER['HTTP_HOST'];
echo $pathName;
?>

Output:

/getting-current-page-url-in-php

Getting Current Page URL in PHP:

so far have seen how to get URL in parts now we are going to combine them to get complete URL in PHP

Example to get Complete URL:

<?php
$pageURL="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $pageURL;
?>

Output:

http://www.designscriting.com/getting-current-page-url-in-php

Please note that we have added “http://” to the final string to make the URL complete.
