Door Opener PHP Code

Some PHP code to handle data to and from an Arduino door opener.

Yes the code is horrible :) this was a quick solution to our missing garage door issue. But it works wondefully!

                                                       |---- LED (on when door open)
                                                       |
 [Web Server + MariaDB + PHP] ----{internet}---- [Arduino(pin)] ----- Magnet Switch on door
                                                       |
                                                       |
                                                       |---{ethernet}--- [Arduino] --- RFID reader outside door

Notes:

• make sure you create a google.cache file and it is writable by PHP if you wish to use Android push notifications.
