Teman-teman Mari Kita Belajar Mengkonversikan Bilangan  ):
Kerjakan di Netbeans yaa ..

1. Masukkan coding berikut dan beri nama Login.php

<?php
if(isset($_POST['submit'])){
$nama=$_REQUEST['name'];
    if(isset($_POST['gender'])){
        $gender=$_REQUEST['gender'];
    }
    else{
        $gender='';
    }
$cek='';
}
else{
    $nama='';
    $gender='';
    $cek='Silahkan Masukkan Data Anda Dengan Lengkap dan Benar :)';
}
?>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>PHP - keonversi bilangan</title>
                <style type="text/css">
            body{
                background-image: url('tugas.jpg');
            }
            .a{
                font-family:Comic Sans MS;
                font-weight:bold;
                color:blue;
                text-align: center;
            }
            .b{
                font-family:Comic Sans MS;
                font-weight:bold;
                color:blue;
                text-align: center;
            }
            form input.highlight{
                background: white;
                padding: 5px;
                text-align: center;
            }
            form input.highlight:focus {
                background: white;
                text-align: center;
            }
        </style>
    </head>
    <body>
      <h1 class='a'>
<?php echo $cek ?></h1>
<br>
        <form action="g.php" method="post" name="form1">
            <p>
<h3 class='b'>
Nama : <input class='highlight' placeholder="Nama Lengkap Anda"
required="required" type="text" name="nama" size ="30" value="<?php
echo $nama ?>"/></h3>
</p>
<p>
<h3 class='b'>
Jenis Kelamin :
                <input type="radio" name="gender" value="L"
                               <?php ($gender=="L")? print
'checked=""' : print ''; ?>/>
                Cowok
                <input type="radio" name="gender" value="P"
                       <?php ($gender=="P")? print 'checked=""' :
print ''; ?>/>
                Cewek
            </h3>
</p>
<center><input type="submit" name="submit" value="Enter"></center>
        </form>
    </body>
</html>


2. Selanjutnya buat new project dengan nama Konverter.php . Tulis coding seperti berikut .

<?php
if(isset($_POST['submit1'])){
$decimal=$_REQUEST['decimal'];
    if(isset($_POST['pilih'])){
        $pilih=$_REQUEST['pilih'];
    }
    else{
        $pilih='';
    }
}
else{
    $decimal='';
    $pilih='';
}
?>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Konversi Bilangan Desimal</title>
                <style type="text/css">
            body{
                background-image: url('tugas.jpg');
            }
            .a{
                font-family:Comic Sans MS;
                font-weight:bold;
                color:blue;
                text-align: center;
            }
            .b{
                font-family:Comic Sans MS;
                font-weight:bold;
                color:blue;
                text-align: center;
            }
        </style>
    </head>
    <body>
            <h1 class="b"Numbers>Konversi Bilangan</h1>
    <?php
        if(isset ($_POST['submit'])){
            $nama=$_REQUEST['nama'];
            if(isset($_POST['gender'])){
                $gender=$_REQUEST['gender'];
            }
            else{
                $gender='';
            }
        }
        if(isset ($_POST['submit'])){
        if($nama==''|| $gender==''){
            echo"<script>

                 document.location.href='l.php';
                 </script>";
        }
        else{
            if($gender=='L'){
                echo"<br><h3 class='a'>

            }
            else{
