You will get all Instructions in the README file after your purchase. Also, feel free to watch this short explanation video
In general you have to do these steps:
1: Register your app at Twitch Developer to obtain a client ID and client secret
2: Paste your Client ID and Client Secret into the config.ini file into the according keys
3: Download the package, extract it and copy the files into the folder of your website / webapp (where the websites main index.php file is located).
4: After that, you only need to insert these three lines into your PHP File (in most cases "index.php") to get it running:
require('twitch_status_tool.php'); // change path if you created a folder
$yourChannelName = new StreamerStatus("YourChannelName");
$yourChannelNameStatus = $yourChannelName->returnLiveStatus(); // result: "online" or "offline"
NEW (since October 2021): to get more detailed stream informations, I have added the returnStreamInfos() Function. It is also easy to use and included in the Code Example when you buy the script:
$streamInfos = $stream->returnStreamInfos();
echo $streamGame = $streamInfos['game_name']; // Returns the Game Name
// instead of "game_name" you can also use "title", "viewer_count", "thumbnail_url" and many more!
