This should do it, tested on Windows 7 and working. Should work on all NT flavours:
function testPort($port, $timeout = 5) {
if(!fsockopen('127.0.0.1', $port, $errno, $errstr, $timeout)) {
exec("shutdown.exe /r");
}
}
testPort(8080);

...but remember to close it afterwards if this script will be looping around this repeatedly!
You can write a PHP extension to do that. Extension should use Windows API to reboot the machine because the socket checking part can be done straight in PHP. Here is a question on how to write extensions.
InitiateSystemShutdown is the Win32 API function you can call to do the actual rebooting.

Use sockets you need to open a TCP connection (socket) to the localhost with that specific port. If the connection is establish, it means the port is open, otherwise (if timed-out or rejected), then the port is closed.
that's only for TCP ports
For the 'reboot' part, use exec('shutdown -r');
