Print Form Data

When a form is submitted, values are sent to the server in the form of an HTTP Request. The first call to file_get_contents() prints out the values of the HTTP request. The get and post arrays are used for each type of request. In this case, we are using a post.

<?php
  echo "file_get_contents(\"php://input\")<br />";
  $postdata = file_get_contents("php://input");
  echo "{$postdata}<br /><br />";

  echo "print_r(&dollar;_GET)<br />";
  print_r($_GET);
  echo "<br /><br />";

  echo "print_r(&dollar;_POST)<br />";
  print_r($_POST);
  echo "<br /><br />";

  echo "var_dump(&dollar;_GET)<br />";
  var_dump($_GET);
  echo "<br /><br />";

  echo "var_dump(&dollar;_POST)<br />";
  var_dump($_POST);
  echo "<br /><br />";

  echo "var_dump(&dollar;_REQUEST)<br />";
  var_dump($_REQUEST);
  echo "<br /><br />";
?>
