how to get the absolute path of a file?

[momotaro]

Hi everyone,

am trying to get the absolute file path of a given document (image) so I can store its path in my database as a string but I can't seem to find how. I user $_FILE no luck. please advise.

Thank you in advance.

I think its wiser to store relative path, relative to the root of your website?

That way you can reinstall everything in a different location, or on a different server more easily
