Simple Twitch query that returns json data of streamers status
Open fetch.php and change the $streamer variable to the streamers username of your choice.
Set a cron job for fetch.php for every minute.
fetch.php will create a json file in the twitch/ directory called status.json which gets updated every minute with your cron job meaning you can skip functions and checks and just use the status.json file for your checks
status.json
{"data":{"streaming":0}}
result.php gets status.json and will set the $streaming variable to 1 for currently streaming and 0 for not streaming.
