• How to send GCM messages to multiple devices at a time 1 answer

i am new to php. i am implementing Firebase push notification service in PHP .

The required json object is like

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

Now in firebase i have to send my data in this format but i am not sure how to make JSON object of this data and use this object in firebase .

And if I want to use Array of IDs then how this will work?

As per official firebase documentation they didn't define method to use array of ID's.

Create an array in a same format that you want to sent to Firebase like bellow

$arr = ['data'=> [
        'score'=> "5x1",
        'time'=> "15:10"
        ],
        "to" => "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
      ];

and then use the php function json_encode(var); and it will return you the json object.

json_encode($arr)

and if i want to use Array of id then how this will work. I am not sure about this.
