          <HTML>

          <HEAD> <TITLE> Using Variables </TITLE> </HEAD>

          <BODY>
          <?php

          $a = true;

          $b = false;

          echo var_dump($a and $b);
          echo "<br>",var_dump($a or $b);

          echo "<br>",var_dump($a xor $b);

          ?>
          </BODY>
