Google Cloud Messaging- Sending Push Message To Android Using PHP

I am working on an android project where I need to push messages using GCM. I wanna send the notification using only PHP and not HTML. How do I achieve this? The way I tried was just putting the gcm_regid and message as parameters to $gcm->send_notification($registration_ids,$msg) but I keep getting an error saying:- Field "data" must be a JSON array: ["You Have A Notification!"]

Where "You Have A Notification!" is my msg!! Please help!! Thanks!

Code for send_notification is

 public function send_notification($registatoin_ids, $message) {

    include_once './config.php';

    // Set POST variables
    $url = 'https://android.googleapis.com/gcm/send';

    $fields = array(
        'registration_ids' => $registatoin_ids,
        'data' => $message,
    );

    $headers = array(
        'Authorization: key=' . GOOGLE_API_KEY,
        'Content-Type: application/json'
    );
    // Open connection
    $ch = curl_init();

    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Disabling SSL Certificate support temporarly
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post
    $result = curl_exec($ch);
    if ($result === FALSE) {
        die('Curl failed: ' . curl_error($ch));
    }

    // Close connection
    curl_close($ch);
    echo $result;
}

}

This is the index.php used for sending the message using the button's on-click. I need to however do this automatically in the background without any button press and want to implement it in PHP.

$fields[] = array(
            'registration_ids' =>$registatoin_ids,
            'data' =>$message
        );

use square braces with $fields this will make it a json array

You will need to embed the registration_id too in array.

$fields = array(
    'registration_ids' => array($registatoin_ids),
    'data' => array("message" => $message),
);

Maybe this will work:

$fields = array(
    'registration_ids' => $registatoin_ids,
    'data' => array("message" => $message),
);
