How Can I Get the URL of the Current Page in PHP?

Get the URL of the Current Page in PHP

In PHP, accessing the URL of the current page is a simple task. This knowledge is particularly useful for tasks such as redirecting users or generating links.

Solution

The $_SERVER superglobal array contains a wealth of information about the current request, including the URL. To retrieve the URL, you can use the following code:

<code class="php">$url = $_SERVER['REQUEST_URI'];</code>

This variable contains the entire URL, including the domain and protocol. If you only need the parts after the domain (e.g., "/example/page.php"), you can use the following:

<code class="php">$url = $_SERVER['REQUEST_URI'];
$parts = explode($GLOBALS['HTTP_HOST'], $url);
$url = $parts[1];</code>

Query String

If you also require the query string (the portion of the URL that appears after the "?" symbol), you can access it using:

<code class="php">$queryString = $_SERVER['QUERY_STRING'];</code>
