set user, havent test this yet

        {
            return FALSE;
        }
        if($role > 255) $role = 255;
        $name = substr($name, 0, 28);
        $command = CMD_USER_WRQ;
        $byte1 = chr((int)($uid % 256));
        $byte2 = chr((int)($uid >> 8));
        $command_string = $byte1.$byte2.chr($role).str_pad($password, 8, chr(0)).str_pad($name, 24, chr(0)).str_pad($card, 4, chr(0)).str_pad(chr(1), 9, chr(0)).str_pad($userid, 8, chr(0)).str_repeat(chr(0),16);

thank you so much sir. I'll try it if found any issue will back to you. thanks

Hi @Tehsseen the code running well??

[Mahfuz2811]

I have solved this problem. Use below code.

public function setUser($uid, $userid, $name, $cardno, $password, $role)
{
    $uid = (int) $uid;
    $role = (int) $role;
    if($uid > USHRT_MAX)
    {
        return FALSE;
    }
    if($role > 255) $role = 255;
    $name = substr($name, 0, 28);
    $command = CMD_USER_WRQ;
    $byte1 = chr((int)($uid % 256));
    $byte2 = chr((int)($uid >> 8));
    //$command_string = $byte1.$byte2.chr($role).str_pad($password, 8, chr(0)).str_pad($name, 28, chr(0)).str_pad(chr(1), 9, chr(0)).str_pad($userid, 8, chr(0)).str_repeat(chr(0),16);

    $cardno = hex2bin($this->reverseHex(dechex($cardno)));
    $command_string = $byte1.$byte2.chr($role).str_pad($password, 8, chr(0)).str_pad($name, 24, chr(0)).str_pad($cardno, 4, chr(0)).str_pad(chr(1), 9, chr(0)).str_pad($userid, 8, chr(0)).str_repeat(chr(0),16);

    return $this->execCommand($command, $command_string);
}

this works!!! eureka!!!!

public function setUserV2($uid, $userid, $name, $password, $role, $card) { $uid = (int) $uid; $role = (int) $role; if($uid > USHRT_MAX) { return FALSE; } if($role > 255) $role = 255; $name = substr($name, 0, 28); $command = CMD_USER_WRQ; $byte1 = chr((int)($uid % 256)); $byte2 = chr((int)($uid >> 8));

    $card = hex2bin($this->reverseHex(dechex($card)));

    $command_string =   $byte1.
                        $byte2.
                        chr($role).
                        str_pad($password, 8, chr(0)).
                        str_pad($name, 24, chr(0)).
                        str_pad($card, 13, chr(0)).
                        //str_pad(chr(1), 9, chr(0)).                           
                        str_pad($userid, 8, chr(0)).
                        str_repeat(chr(0),16);

    return $this->execCommand($command, $command_string);
}

this works!!! eureka!!!!

public function setUserV2($uid, $userid, $name, $password, $role, $card) { $uid = (int) $uid; $role = (int) $role; if($uid > USHRT_MAX) { return FALSE; } if($role > 255) $role = 255; $name = substr($name, 0, 28); $command = CMD_USER_WRQ; $byte1 = chr((int)($uid % 256)); $byte2 = chr((int)($uid >> 8));

  $card = hex2bin($this->reverseHex(dechex($card)));

  $command_string =   $byte1.
                      $byte2.
                      chr($role).
                      str_pad($password, 8, chr(0)).
                      str_pad($name, 24, chr(0)).
                      str_pad($card, 13, chr(0)).
                      //str_pad(chr(1), 9, chr(0)).                           
                      str_pad($userid, 8, chr(0)).
                      str_repeat(chr(0),16);

  return $this->execCommand($command, $command_string);
}
