A

If you want list all values of submitted fields, you can write a simple loop to retrieve all entries in the $_REQUEST array. Below is an improved version of processing_forms.php to list all submitted input values:

<?php
  print("<html><pre>");
  $count = count($_REQUEST);
  print("Number of values: $count\n");
  foreach ($_REQUEST as $key=>$value) {
    print("  $key = $value\n");
  }
  print("</pre></html>\n");
?>

If you test this with submit_comments.php on your Web server, you will get something like:

Number of values: 2
  name = Fyi Center
  comment = Good job.
