Hi there

I think you need to change this function

public function clearAttendance(){
        $command = CMD_CLEAR_ATTLOG;
        return $this->execCommand($command);
}

with this function, this is working perfectly fine with (ZK uFace 800) and I think this also working with other types

function clearAttendance() {
        $command = CMD_CLEAR_ATTLOG;
        $command_string = '';
        $chksum = 0;
        $session_id = $this->session_id;

        $u = unpack('H2h1/H2h2/H2h3/H2h4/H2h5/H2h6/H2h7/H2h8', substr( $this->received_data, 0, 8) );
        $reply_id = hexdec( $u['h8'].$u['h7'] );

        $buf = $this->createHeader($command, $chksum, $session_id, $reply_id, $command_string);

        socket_sendto($this->socket, $buf, strlen($buf), 0, $this->ip, $this->port);

        try {
            socket_recvfrom($this->socket, $this->received_data, 2048, 0, $this->ip, $this->port);

            $u = unpack('H2h1/H2h2/H2h3/H2h4/H2h5/H2h6', substr( $this->received_data, 0, 39 ) );

            $this->session_id =  hexdec( $u['h6'].$u['h5'] );
            return substr( $this->received_data, 39 );
        }catch(exception $e) {
            return False;
        }
    }
