PHP: How to find my url?

BrianK · 02-08-2006, 07:14 PM

Is there a way to find the URL of a php doc from within the php doc without going through a post or get step? I know I can use the global $HTTP_REFERER, but that only works once data has been posted via a form - not if I just land on the page by typing it in.

So you want the URL of the current page, right? Just check the documentation for the $_SERVER superglobal. You can use $_SERVER['REQUEST_URI'], $_SERVER['PHP_SELF'], and several other as well. Of course, those only give you the path, not the hostname. For that, you need $_SERVER['HTTP_HOST'].

Got it ... to a degree ...

$REQUEST_URI is the full path to the php doc, including get args. Some assembly will give back the full URL including get args.

If there's a better solution, feel free to chime in.

hehe... posted at the same time.

Thanks for the page on $_SERVER - hadn't seen that yet.

www.php.net is your friend..i practically live there...hehe. the best way i have found to get the correct items for this is to have a page display phpinfo(). if the page containing <?php phpinfo();?> is called say, info.php for example. call the page by typing, in url: http://yourpage.com/info.php?you=rock&php=iscool, and then you can see the difference between say PHP_SELF and REQUEST_URI, and you can see all of the other attributes of $_SERVER and the like
