 # Simple web page to accept GET's from IFTTT or any other webhook provider

 # Was originally intended to push messages from my Ring door bell to MQTT.

 # Examples:
 #
 # GET http://localhost/ifttt-mqtt.php??thing=doorbell&time=now&kind=ring
 #
 # Can be used in a IFTTT recipe with a Ring doorbell.

 # Requirements:
 #
 # Any vaguely new version of PHP, and the MQTT library from here:
 # https://www.cloudmqtt.com/docs-php.html
