Description:
------------
Environment: XAMPP 1.7.3 with Apache HTTPD 2.2.14 and PHP 5.3.1 on Windows XP SP3.

Problem: $_SERVER['SERVER_NAME'] incorrectly returns the HTTP Host header.

The $_SERVER['SERVER_NAME'] is supposed to return the server name as definied in the webserver. In this case, the ServerName property of Apache HTTPD's httpd.conf. It instead returns the HTTP Host header.

This is likely a bug in the php5_module used. There was a similar bug report earlier http://bugs.php.net/bug.php?id=16867 but it was forwarded to Apache developers while the problem is likely in the php5_module.

As explained in the bug you are referencing, PHP doesn't set this at 
all.  The value comes from the web server.  If it is not set correctly, 
it is because your web server got it wrong.

It's 5 year old and I don't seem to find anything related at the bug database of the Apache guys. Is the php5_module really doing things right? Is it querying the right key value from the Apache Server? I'll file a bug to the Apache guys anyway.

Right:

http://httpd.apache.org/docs/2.2/mod/core.html#usecanonicalname

Sorry for the inconvenience. I would however opt to take this info in the PHP documentation about SERVER_NAME.
