Issue with iPXE and PHP

[thomil]

When exactly does iPXE hang? Right it fetches your php page and tries to execute it?

If that's the case please enter the iPXE command line, fetch the image manually and execute 'imgstat':

dhcp
kernel http://bs1/boot.php?mac=${net0/mac}
imgstat

It should say something like "Script" next to that file. It probably says "PXE" or "NBP" or something similar instead. If that's the case you may have some issues with iPXE incorrectly detecting the shebang line("#!ipxe"). Is there maybe some issue with the character encoding? Is the very first thing that script outputs really "#!ipxe\n" with absolutely nothing before it? You should also check with a browser that the content type really is text/plain.
