PHP based wpa_cli interface for WPA Supplicant

• configure the interface for use in the $iface variable
• create an instance of the wpa_cli php class in a compatible environment
• use some of the provided commands or execute commands to wpa_cli via the wpa_shell function

Originally developed for use with the Raspberry Pi, but implementation should be possbile for other type of systems. The user running the webserver should have access to the wpa_cli, ifup and ifdown binaries in order for them to be executed. On a Debian system, this is easy with the visudo command that edits the priviliges file for the user accounds. Adding the following line to the file would enable the access to the www-data user:

www-data ALL=(ALL) NOPASSWD:/sbin/wpa_cli,/sbin/ifup,/sbin/ifdown

demo.php contains example usage of displaying the status of the network interface and performs a scan, followed with the results
