not getting the ServerName in the $_SERVER[SERVER_NAME]

[klehonia]

Hi, i have a php server on iis6 win2003. When i write in index.php <? phpinfo(); ?> it brings me the information of php server _SERVER["SERVER_NAME"] the name of localhost, but when i write the variable $_SERVER['SERVER_NAME'] i get an error PHP Notice: Undefined index: SERVER_NAME. Any ideas please? Is something to do with the php.ini or with the environment variables like DOCUMENT_ROOT?
Thank you.

Try:

echo ("<pre>");
print_r($_SERVER);
echo ("SERVER = " . $_SERVER['SERVER_NAME']);
echo ("</pre>");

And see if it displays in that array. Im sure I read somewhere once that IIS can act differently due to an old spoofing vuln with the $_SERVER['SERVER_NAME'] variable so your problems could be related to that. .

As an alternative, see if you can use $_SERVER['HTTP_HOST']

Cheers.

Heya, klehonia.

$_SERVER['SERVER_NAME'] is populated by Zend Platform. A stock PHP installation generally won't have this variable accessible.

Try $_SERVER['HTTP_HOST'] instead. You might have to explode('.') it if you only want a specific part of it.
