php - Server Sent Events triggered by receiving API POST -


i'm trying watch event notifications google calendar api's trigger endpoint php file: 

use sse\event; use sse\sse;  //create event handler class youreventhandler implements event {     public function update(){         //here's place send data         return 'hello, world!';     }      public function check(){         //here's place check when data needs update      if ($_server['request_method'] == 'post') { // trigger on api post request - not working         foreach($_server $name => $value)         {             if (strpos($name, 'goog') !== false)             {                 //return ("\$_server['$name'] => $value"); // skriv ut verdien med variabelnavnet og innholdet den.                 return true;             }         }     }     //return true;     } } $sse = new sse(); //create libsse instance $sse->addeventlistener('event_name', new youreventhandler());//register event handler $sse->start();//start event loop ?>

i using libsse-php library https://github.com/licson0729/libsse-php

problem: post message google api correctly verified ok sending received headers error.log, i'm not able trigger endpoint php file in way client file stream getting triggered:

var sse = new eventsource('/notifications/notification-endpoint.php'); sse.addeventlistener('event_name',function(e){     var data = e.data;     //handle data here     console.log('her kommer data!!')     console.log( data ) },false);

hope feedback on how fetch post headers external api's trigger php endpoint purpose of triggering sse.
