Send Firebase Message

For mobile apps, you can send Firebase messages via Google's API using the Apex\Mercury\Firebase\Firebase class. You must already have a Google account setup with this ability.

FirebaseConfig

You must create an instance of the Apex\Mercury\Firebase\FirebaseConfig class with your API details to send Firebase messages. The constructor accepts the following parameters:

Variable	Required	Type	Description
$project_id	Yes	string	The project ID.
$server_key	Yes	string	The server key.
$sender_id	Yes	string	The sender id.
$app_name	No	string	The app name.
$firebase_url	No	string	The API URL to send to. Defaults to https://fcm.googleapis.com/fcm/send

All above parameters will be obtained from your Google account.

Sending Firebase Messages

You may send Firebase messages by calling the Apex\Mercury\Firebase\Firebase::send() method, after instantiating the class with passing a FirebaseConfig object to the constructor. The send() method accepts the following parameters:

Variable	Required	Type	Description
$message	Yes	string	The message / payload to send, generally a JSON object.
$android_ids	No	array	An array of Android device IDs to send to.
$ios_ids	No	array	An array of iOS device IDs to send to.
$type	No	string
$title	No	string
$icon	No	string
$action_id	No	string

This will return an integer with the total number of messages successfully sent. For example:

use Apex\Mercury\Firebase\{Firebase, FirebaseConfig};

// Get config
$config = new FirebaseConfig(
    project_id: 'project_id', 
    server_key: 'server_key', 
    sender_id: 'sender_id'
);

// Send Firebase message
$firebase = new Firebase($config);
$count = $firebase->send("Message to send", ['android-device-id', 'android2']);

echo "Sent total: $total\n";
