How to make an absolute URL?

Hi, I am working on file uploads and I ened to save the new photo location in a database.
So what i want to do is, move the file one folders up, and then make that an absolute URL to save into the database.
Example:
Current Page: site.com/photos/upload/photo.php
Where I want the photo to go: site.com/photos
What I want saved to the database: site.com/photo/photo.jpg

 

/your/web/path/site.com/photos/save.jpg

?

 

Oh sorry, i wanted it to be able to used on more than one site of mine, thats why I can't specifically set the URL, I need the script to do that based on the current URL

 

Ahh, you could:

1. Create a config variable for the user photo path (full server path)
2. Use this: $photo_path = $_SERVER['DOCUMENT_ROOT'].'/photos';
3. Try relative pathing: ../../photos (etc.)

 

Ok, so if my page is: http://site.com/upload/photo.php
And I do $_SERVER[SCRIPT_FILENAME] it returns something like:
home/fawfw/awfawfaw/fwaaf
How do I get the actual url like:
http://site.com/upload/photo.php

 

thanks all!
I got what i needed
