使用php if语句的html代码[关闭]

I have the following problem:

I would like to show and hide input fields when a variable from the PHP script is set. Further it will include a second condition which also will show or hide another input field.

I would like to know if something like this is possible:

<?php if(isset($var) && $var =="S0"):?>
  <div>
     inputfield1        
  </div>

  <?php if(isset($var) && ($var =="S0" || $var =="S2"):?>
      <div>
         inputfield2        
      </div>
  <?php endif; ?>
  <div>
     inputfield3        
  </div>
<?php endif; ?>

You have missing 1 bracket in second condition

<?php if(isset($var) && ($var =="S0" || $var =="S2")):?>
