This code contains the main function of the application. This code will convert the money value when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as convert.php

  1. <?php
  2. if(ISSET($_POST['convert'])){
  3. $val = $_POST['val'];
  4. $digit = $_POST['digit'];
  5. $currency = $_POST['currency'];
  6.  
  7.  
  8. if($val=="PHP" && $currency=="USD"){
  9. $output = $digit * 51.52;
  10. echo"<center><label class='text-success' style='font-size:25px;'>$".$output."</label></center>";
  11. }else if($val=="PHP" && $currency=="Euro"){
  12. $output = $digit * 63.62;
  13. echo"<center><label class='text-success' style='font-size:25px;'>&#8364;".$output."</label></center>";
  14. }else if($val=="PHP" && $currency=="PHP"){
  15. $output = $digit;
  16. echo"<center><label class='text-success' style='font-size:25px;'>&#8369;".$output."</label></center>";
