Variabel PHP Nama variabel diawali dengan tanda $ <?php $x=5; $y=7; $z=$x * $y; echo “$z”; ?>
Jawaban Latihan <table border=1> <tr><td>x<td>y<td>z <?php $x=2; $y=3; $z=$x+$y; echo “<tr><td>$x<td>$y<td>$z”; ?> </table>
Perulangan <?php echo “<table border=1>”; for($x=0;$x<10;$x++){ echo “<tr><td>$x”; } echo “</table>”; ?>
Latihan Buat tabel perkalian 10x10
Pencabangan <?php $loop=1; while($loop<10){ echo “$loop – “; if(($loop % 2) == 0) { echo “<br>”; } $loop=$loop+1; ?>
