How to find out that the timer has fired on the descriptor created in the stream_socket_client function?

Question

PHP

Actually, the data is transferred by the fwrite function, you need to somehow find out if the write on the socket was interrupted by a timer.

function __construct($address, $remote_port, $timeout)
  {
    $this->address = $address;
    $this->port = $remote_port;
    $this->timeout = $timeout;
    $this->fp = stream_socket_client("tcp://".$address.":".$remote_port, $errno, $errstr, $timeout);
  }
  public function Send($msg)
  {
    if (!$this->fp)
    {
      fclose($this->fp);
      return false;		
    }
    else
    {
      //Здесь нужно как то обработать ошибку таймера
      //if (fwrite($this->fp, $msg) == TIMEOUT)
      // return TIMEOUT// Что то в этом роде нужно произвести
      fwrite($this->fp, $msg);
    }
    return true;
  }
