For the error reporting system I am trying to get some info onto the
name of the server currently running. I am using the server signature
to try and find the server and its version. I however have only apache
so I was wondering if someone with nginx or IIS would run the
following php script and reply with the output so that I am able to
see the output of different server softwares so as to craft my regular
expression.

<?php
echo $_SERVER["SERVER_SOFTWARE"];
echo "\n\n";
echo $_SERVER["SERVER_SIGNATURE"];
