";

    $headers = array('Authorization:key=' . $yourKey);    
    $data = array(    
        'registration_id' => $deviceToken,          
        'collapse_key' => $collapseKey,
        'data.message' => $messageText);  
    $ch = curl_init();    

    curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");    
    if ($headers)    
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    
    curl_setopt($ch, CURLOPT_POST, true);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    

    $response = curl_exec($ch);    
    var_dump($response);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);    
    if (curl_errno($ch)) {
        return false;
    }    
    if ($httpCode != 200) {
        return false;
    }    
    curl_close($ch);    
    return $response;    
}  

$yourKey = "YOURKEY";
$deviceToken = "REGISTERED_ID";
$collapseKey = "COLLAPSE_KEY";
$messageText = "MESSAGE";
echo sendMessageToPhone($deviceToken, $collapseKey, $messageText, $yourKey);
?>

In above script just change :

"YOURKEY" to API key to Server Key of API console.
"REGISTERED_ID" with your device's registration ID
"COLLAPSE_KEY" with key which you required
"MESSAGE" with message which you want to send

Let me know if you are getting any problem in this I am able to get notification successfully using the same script.
