Trailing backslash at domain in URLs when installed in DocumentRoot

• Error
• Patch

In my installation, on some internal links that are represented in an absolute way, there is a backslash between the domain name and the first slash.

Eg when I try to login on http://mydomain.com/index.php, I get redirected to http://mydomain.com\/tiki-login.php, which the server cannot render.

Clean install of:
MS Windows Server 2003 SE SP2 on x86
Apache 2.2.10
MySQL 5.1.30
PHP 5.2.8
TikiWiki 2.2

Tiki resides directly in the DocumentRoot C:\tiki (as it is a dedicated server).

In tiki-setup.php, there is a line

$tikiroot = dirname($_SERVER['PHP_SELF']);

In the documentation of dirname, they state that since PHP 4.3.0, dirname returns unexpected values. The example implies that on Windows dirname('/x') returns '\'.

Therefore, if you install Tiki in the DocumentRoot, _SERVER'PHP_SELF' will be '/filename.php' and $tikiroot will be '\'.

Since this seems to be the only special case, adding

if ($tikiroot == '\\\\') $tikiroot = '/';

somewhere appropriate, eg before

if ( substr($tikiroot,-1,1) != '/' ) $tikiroot .= '/';

works for me. Otherwise, a regex should help. However, I'm not too familiar with Tiki's source; maybe there are other places.
