How can PHP be used to send Twitch messages?

To send Twitch messages using PHP, you can utilize the Twitch API to authenticate your application and send messages on behalf of a user. You will need to obtain an OAuth token and use it to make API requests to send messages to Twitch chat.

<?php
$token = 'YOUR_OAUTH_TOKEN';
$channel = 'CHANNEL_NAME';
$message = 'Hello from PHP!';

$url = 'https://api.twitch.tv/kraken/chat/' . $channel . '/messages';
$headers = [
    'Client-ID: YOUR_CLIENT_ID',
    'Authorization: OAuth ' . $token,
    'Content-Type: application/json'
];

$data = [
    'content' => $message
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>
