Lack of Trailing Slash in IIS PHP _VARIABLES

[dcmbrown]

So we're recoding a site to bring it from Linux/Apache/PHP to Windows/IIS/PHP and are encountering the following problem.

When using various server variables, when doing something like:

print $_SERVER['DOCUMENT_ROOT']."/path/to/file.jpg";

It comes out as this on Linux/Apache/PHP

/sites/domain/htdocs/path/to/file.jpg

But on Windows (or just in IIS) it comes out as:

/sites/domain/htdocspath/to/file.jpg

Is there something in the IIS/PHP php.ini I can do to change this behaviour?

print $_SERVER['DOCUMENT_ROOT']."/path/to/file.jpg";

That prints without a slash before "path"? I really don't see how.

Also, I've never seen $_SERVER['DOCUMENT_ROOT'] show up with a trailing slash on Windows or Linux Apache, or on IIS. What versions server and PHP are you using?
