Koverter Bilangan Desimal dengan Menu Pilihan

 Langkah Perdana buwatlah file validator !
caranya : Klik kanan ~> New File ~> PHP web page
kalo belum tau codingnya boleh copas :D
if(isset($_POST['submit'])){//isset : penekanan form
$nama=$_REQUEST['nama'];
    if(isset($_POST['gender'])){
        $gender=$_REQUEST['gender'];
    }
    else{
        $gender='';
    }
$cek='';
}
else{
    $nama='';
    $gender='';
    $cek='Sebelum datang, monggo login dulu :D';
}
?>
