PHP Script: scan for wireless networks + small features

Hello freelancers! I'm looking for someone that will write me a simple PHP script. It needs to: 1. Show a loading gif (turning circle, or whatever) indicating that it is scanning for wifi networks. 2. List all WiFi networks in a form dropdown select list. 3. Have a button that will re-scan for WiFi networks, when finished, update the dropdown select list No graphics or designing needed, just the script(s)!
