Newbie - equivalent of MapPath in PHP? 1

[whinger74]

Hi,
I'm used to programming in ASP, and my site is hosted with a commercial host.
Can somebody please tell me how can I find out the physical rather than virtual path of file? i.e. in ASP I would use <%=Server.MapPath %>

Thank you anyone!

Thanks!
<?php echo $_SERVER['PATH_TRANSLATED'] ?> will produce the same result aswell
After a search of php.net I was eventually successful, even though I didn't really know what exactly I was looking for!!

Actually, PATH_TRANSLATED doesn't work in all cases. PATH_TRANSLATED's little brother is called PATH_INFO and basically here's an example of how it works:

Imagine you have a PHP script that lets users download files on the server... but it does additional things like tracking usage and telling them "Your download will start momentarily". The name of your script will be retrieve.php.

To download a file, the requested file is added on to the end of it, for example:

http://www.server.net/retrieve.php/images/billgates.jpg

Now the part following retrieve.php--the "/images/bill.jpg" part--is goes into $_SERVER['PATH_INFO'].

Now, $_SERVER['PATH_TRANSLATED'] is that part as an absolute path relative to the document root. In the previous example PATH_TRANSLATED would be something like /var/

http://www/htdocs/images/billgates.jpg.

But if there is no PATH_INFO in the URL, I guess PATH_TRANSLATED could be the same as SCRIPT_FILENAME, though you shouldn't count on it.
