Belajar PHP

Cara mengenerate sel tabel secara fleksibel dapat kita lakukan dengan membuat dua buah file yang berektensi *.html dan *.php. Source Codenya seperti dibawah ini :

Source Code *.html :

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<html>

<head>
<title>Tabel Generate</title>
<style type="text/css">
<!--
#a1 {
    width: 180px;
    height: 25px;
    z-index: 1;
    left: 285px;
    top: 190px;
}
    color: white;
.b1 {
    font-weight: bold;
}
-->
</style>
</head>

<body>

<script language="JavaScript" type="text/javascript">
function getmax() {
    var R = parseInt(document.getElementById('JumlahRow').value);
    var C = parseInt(document.getElementById('JumlahColum').value);
    var X = parseInt(document.getElementById('JumlahCell').value);
    var cellmax = document.getElementById('maxcells');
    var total = 'N/A';
    total = R * C; 
    cellmax.value = new String(total);
    if (X > total)
    {
        alert('Cell Total Yang Anda Masukkan Terlalu Besar, Nilai Maksimum Cells = ' + total);
        document.getElementById('CellsTotal').value = new String();
    }
}
</script>

<form method="post" action="generate.php">
  <h3 class="b1">Program Generate Sel Tabel Secara Fleksibel</h3>
  <div>
    <table width="300" border="0" bgcolor=blue>
      <tr bgcolor="white">

      </tr>
    </table>
  </div>
  <div id="a1">
  <input type="submit" name="Generate" value="Generate"/>
  <input type="reset" name="Reset" value="Reset"/>
  </div>
</form>

</body>
</html>



Source Code *.php : 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<html>

?>

  <?php $rows = (int) $_POST["JumlahRow"]; ?>
  <?php $columns = (int) $_POST["JumlahColum"]; ?>
  <?php $cells = (int) $_POST["JumlahCell"]; ?>

  <strong>Anda Membuat</strong> <?php echo $rows; ?> <em>baris,</em><br />
  <strong>Anda Membuat</strong> <?php echo $columns; ?> <em>kolom,</em><br />
  <strong>Dan Anda Menampilkan</strong> <?php echo $cells; ?> <em>sel tabel,</em><br />
  <br />
  <br />
  <?php
    $width = $columns * 75;
    echo "<table width=".$width." border=1>";
    $rw = 0;
    $cel = 1;
    while ($rw < $rows && $cel <= $cells)
