how can i test php api in firebase.google.com - firebase

Question

I am working in php project to send pushnotification. I have signup and get api key at https://console.firebase.google.com. I have also get following code from some reference site.
/*
Parameter Example
$data = array('post_id'=>'12345','post_title'=>'A Blog post');
$target = 'single tocken id or topic name';
or
$target = array('token1','token2','...'); // up to 1000 in one request
*/
function sendMessage($data,$target){
//FCM api URL
$url = 'https://fcm.googleapis.com/fcm/send';
//api_key available in Firebase Console -> Project Settings -> CLOUD MESSAGING -> Server key
$server_key = 'AIzaSyBY5ZTQiCrFY6Syq9oymtlJODcwvkGyxmI';
$fields = array();
$fields['data'] = $data;
if(is_array($target)){
$fields['registration_ids'] = $target;
}else{
$fields['to'] = $target;
}
//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_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
if ($result === FALSE) {
die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
return $result;
}
But my query is that how can i use it ? i means how can i get target/token to test ? can i get this required token without android ? Is there any console where i can get test token for specific mobile. I want to test above code and so.

In the application you will have a class that extends FirebaseInstanceIdService
Overwrites the following method and run the code
private static final String TAG = "MyFirebaseIIDService";
#Override
public void onTokenRefresh() {
//Getting registration token
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
//Displaying token on logcat
Log.d(TAG, "Refreshed token: " + refreshedToken);
}
it displays the token on the AndroidStudio console
