Getting error while receiving an FCM push notification using PHP - php

Question

I want to send notification using FCM. I have added project to Firebase Console got the API key and device_token.
Now I am sending a push notification from PHP, I get the message in logs, but it's showing some exception. I have followed this tutorial.
PHP script function:
function sendInvite()
{
$database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
$dbConnection = $database->getDB();
$stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?");
$stmt->execute(array($this->user_name,$this->sender_id));
$rows = $stmt->rowCount();
if ($rows > 0) {
$response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name);
return $response;
}
$this->date = "";
$this->invitee_no = "";
$this->status = "0";
$this->contact_id = 0;
$stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id) values(?,?,?,?,?,?)");
$stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id));
$rows = $stmt->rowCount();
$Id = $dbConnection->lastInsertId();
$stmt = $dbConnection->prepare("Select device_id from Users where user_id =?");
$stmt->execute(array($this->sender_id));
$result = $stmt->fetch(PDO::FETCH_ASSOC);
$token = $result["device_id"];
$server_key = 'AIzaJaThyLm-PbdYurj-bYQQc';
$fields = array();
$fields['data'] = $data;
if(is_array($token)){
$fields['registration_ids'] = $token;
}else{
$fields['to'] = $token;
}
//header with content_type api key
$headers = array(
'Content-Type:application/json',
'Authorization:key='.$server_key
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);

}
curl_close($ch);
echo $result;*/

What's going wrong here?
I also want to make notification responsive. As it should have Accept and Reject option and on click of that, I want to perform an action.
Can anyone help with this please? Thank you..

Try with below example with manually device token pass
<?php
define("ANDROID_PUSHNOTIFICATION_API_KEY",'API_KEY_HERE'); // FCM
define("ANDROID_PUSHNOTIFICATION_URL",'https://fcm.googleapis.com/fcm/send'); // FCM
function push_android($devicetoken,$param){
$apiKey = ANDROID_PUSHNOTIFICATION_API_KEY; //demo
$registrationIDs[] = $devicetoken;
// Set POST variables
$url = ANDROID_PUSHNOTIFICATION_URL;
$fields = array(
'registration_ids' => $registrationIDs,
'data' => $param,
);
$headers = array(
'Au
thorization: key=' . $apiKey,
'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 );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
// Execute post
$result = curl_exec($ch);
//print_r($result); exit;
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}else{
//echo "success notification";
//print_r($result);
//echo curl_error($ch);
}
// Close connection
curl_close($ch);
return $result;
} ?>
Hope this will help!

Answer 2

This exception is thrown when you have used special characters.Try removing the , before the fullstop.
And to make it responsive like adding accept and reject you can look into the firebase documentation
this is a good explanation
