How to print all information from an HTTP request to the screen, in PHP

Question

I need some PHP code that does a dump of all the information in an HTTP request, including headers and the contents of any information included in a POST request. Basically,

Answer 1

A simple way would be:

<?php
print_r($_SERVER);
print_r($_POST);
print_r($_GET);
print_r($_FILES);
?>

A bit of massaging would be required to get everything in the order you want, and to exclude the variables you are not interested in, but should give you a start.

Answer 2

Lastly:

print_r($_REQUEST);

That covers most incoming items: PHP.net Manual: $_REQUEST

Answer 3

Well, you can read the entirety of the POST body like so

echo file_get_contents( 'php://input' );

And, assuming your webserver is Apache, you can read the request headers like so

$requestHeaders = apache_request_headers();
