Many PHP examples out there are designed for a linux/unix operating system. I am going to give some examples of some interesting functionality that only works with php running in a windows environment (IIS or apache).

Here's the list:

• Eject the CD-ROM
• Read and write from/to the registry
• Register and un-register phpscripts as a windows service
• Print pages/data
• List the current system processes

Each item has sample code and a simple explanation to get you started using it.
