Form Input in PHP

Very straightforward; form input is stored in variables with the same name as the input tag's name attribute, as here:

<?php
 if ($lang=="") {
  ?>
   Pick one:<br>
   <a href="php6.php?lang=FORTRAN">FORTRAN</a><br>
   <a href="php6.php?lang=APL">APL</a><br>
   <a href="php6.php?lang=Java">Java</a><br>
   <a href="php6.php?lang=VisualBASIC">VisualBASIC</a><br>
  <?php
 } else {
   print "Derek's favorite language is $lang.<br>";
 }
?>

Pick one:
FORTRAN
APL
Java
VisualBASIC
"; } ?>
