In PHP, we can get current page url using `$_SERVER` built-in superglobal variable. Assume that the current url is `https://www.cluemediator.com/category/php/blog.php`.
We will learn the functions below to get the parts and full url of the current page.
1. $_SERVER['HTTPS']
Using `$_SERVER['HTTPS']`, we can check the protocol is http or https.
$protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https://" : "http://");
echo $protocol;
// Output: https://
2. $_SERVER['HTTP_HOST']
To get Host (Domain name), we will use `$_SERVER['HTTP_HOST']`.
$host = $_SERVER['HTTP_HOST'];
echo $host;
// Output: www.cluemediator.com
3. $_SERVER['REQUEST_URI']
To get the full path of a page, we will use `$_SERVER['REQUEST_URI']`.
$path = $_SERVER['REQUEST_URI'];
echo $path;
// Output: /category/php/blog.php
Finally to get full current page url, we can write the code like below.
$protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https://" : "http://");
$getUrl = $protocol.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $getUrl;
// Output: https://www.cluemediator.com/category/php/blog.php
4. $_SERVER["QUERY_STRING"]
If you want to get query from the url, you can use `$_SERVER["QUERY_STRING"]`. let's take one example if current url is `https://www.cluemediator.com/category/php/blog.php?id=1&cat=2`.
$query = $_SERVER["QUERY_STRING"];
echo $query;
// Output: id=1&cat=2
That’s it for today.
