PHP: How do I get the URL a file is in?

Question

I can't seem to find a super-global for this. Basically, if a PHP file is executed on, say, http://www.example.com/services/page.php, I would like to retrieve http://example.com/services. How do I achieve this?

Answer 1

You can abuse dirname:

<p>
<?php echo $_SERVER["HTTP_HOST"] . dirname($_SERVER["REQUEST_URI"]) ?>
</p>

Answer 2

Take a look at $_SERVER['HTTP_HOST'] and $_SERVER['REQUEST_URI']. HTTP_HOST would contain the host name the resource was requested from an REQUEST_URI URI path and query that was requested.
