function send_fcm($tokens,$message)
          {

	    $url = 'https://fcm.googleapis.com/fcm/send';
	    $priority="high";
	  
	
	    $fields = array(
	         'registration_ids' =>$tokens,         
	          'data' =>$message
	           
	        );

	 
		   $headers = array(
		        'Authorization:key=your key',
		        'Content-Type: application/json'
		        );

		   $ch = curl_init();
		   curl_setopt($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));
		 echo  json_encode($fields);
		   $result = curl_exec($ch);           
		   curl_error($ch);
		   if ($result === FALSE)
		    {
		       die('Curl failed: ' . curl_error($ch));
   		    }
                  curl_close($ch);
                  return $result;
             }
