  1. <?php
  2. if(ISSET($_GET['word']) && !empty($_GET['word'])){
  3. if(ctype_lower($_GET['word'])){
  4. $word=$_GET['word'];
  5. $upper_word=strtoupper($word);
  6. echo "<h2 class='text-danger'>".$upper_word."</h2>";
  7. }else if(ctype_upper($_GET['word'])){
  8. $word=$_GET['word'];
  9. $lower_word=strtolower($word);
  10. echo "<h2 class='text-danger'>".$lower_word."</h2>";
  11. }
  12. }
  13. ?>
