How to get current page url in PHP ?

The goal of this article is to give you a piece of code that allows you to get the URL of the current visited page. But you will need some knowledge of PHP or programming languages ​​to get by.

To obtain the URL of the web page displayed, you will need to retrieve three pieces of information in your script:

The protocol used by the web server: http or its secure version, https using the $ _SERVER variable, PHP variable which contains a lot of information about the server. We will therefore use $ _SERVER [‘HTTPS’] to find out if the server is using the secure version of http or not.

The domain name of the site using $ _SERVER [‘HTTP_HOST’] which allows you to retrieve the domain name of the site of the visited page (or by default its IP address if the site does not have a domain name).

The current page you are visiting. If you just want to get the page, preferably use $ _SERVER [‘PHP_SELF’]. However, it can be very useful to retrieve the parameters of the query, that is, anything after the question mark (?). Ex: index.php? Categorie = 3 & page = 2 In this specific case, we will rather use $ _SERVER [‘REQUEST_URI’] to obtain the full URL of the current page.

Here is my code to get the address of the current page:

// get the protocol
if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on') $url = "https://"; else $url = "http://";
// get IP address
$url .= $_SERVER['HTTP_HOST'];
// get the URI
$url .= $_SERVER['REQUEST_URI'];
// displays the URL of the current page
echo $url;

I hope this has been useful to you!
