Trying to get a full URL without filename in PHP
<p>I thought this would be simple but I can't seem to find a variable of $_SERVER array that has what I'm looking for.</p>

<p>Let's say my url is "http://example.com/subdirectory/index.php"   I want to get all but the filename - "http://example.com/subdirectory/".</p>

<p>I know I could quite easily do this with some string manipulation, but I want to know if there's a var of the _server array that I'm just missing.  I've tried all of them to see what they give and I can get anything BUT what I'm looking for.</p>
