PHP logic not working

I'm trying to get iPXE working with PHP and MYQSL.

For some reason the PHP logic does not seem to be working.

I've got the following code in a php file that ipxe chain boots:
What its supposed to do is grab the serial number of the server and assign it to the variable: serversn

Code:

<?php
header("Content-type: text/plain");
echo "#!ipxe\n\n";

$serversn = "\${serial}";

I think the problem is the calling factor. ${serial} is a place holder for the iPXE calls, so can the reason why the output is 9 characters is because the actual information stored in serversn is:
${serial}, literally. Which, as it happens, is 9 characters.

The way I pass variables like such back to my php scripts is to send it back in the url.

So I might have something like:

PHP Code:

print "#!ipxe\n";
print "chain http://192.168.1.2/boot.php?serversn=\${serial}\n"; 


Then I use the GET or POST var of servsn, this should now be set to the serial, not literally set to ${serial}.

So my Logic would contain, to check it, something like:

PHP Code:

if ($_GET['serversn'])
{
print "#!ipxe\n";
print "echo My system's serial number is: ....".$_GET['serversn']."\n";
} 


Hope this helps.
