PHP doesn't access root directory using forward slash "/"

[ECRIA]

Hi All,

We are trying to figure out why PHP's file handling functions refuses to
access the web root using the "/" character on our Windows machines. For
example, a file /test.php is located in our web root. A file in a
subdirectory, say /example/runme.php needs to find out if the file
"/test.php" exists. One would expect that the function
file_exists("/test.php") would return true (it does on our unix host).
However, it returns false on our Windows machine.

Unfortunately we can't build a workaround as it is not us but oscommerce
that uses the "/" method to refer to the web root, and modifying all the
oscommerce scripts is simply impractical.

Any pointers would be greatly appreciated,

Hi

On Windows this is not a valid Path "/test.php". If you want to test
for a file aon the
local directory use "./test.php" otherwise if you want to test for a
file on your web root you should set a specific DOCUMENT ROOT depending
on your webroot in apache. Then you could use

if(file_exists($_SERVER['DOCUMENT_ROOT']."/test.php"){
echo "Yipee;
}
Good luck

file_exists works in the filesystem space, not the URL space of the webserver.
"/" never refers to the web root (unless your webserver was chroot'ed to the
web root, which would be unusual); it's the filesystem root.

On Windows this is further complicated because there are multiple roots, one
per drive; "/" is a relative path on Windows, not an absolute path - relative
to the drive of the current working directory.
