Quick PHP debugging when you want to know what an API or whatever sends to you. And some other stuff.

incoming.php

<?php
// Remember to delete the emails, if you are not planning on removing some of the arrays below.
$message = "Results HEADER:\n" . print_r( getallheaders(), true );
$message .= "Results SERVER:\n" . print_r( $_SERVER, true );
$message .= "Results GET:\n" . print_r( $_GET, true );
$message .= "Results POST:\n" . print_r( $_POST, true );
$message .= "Results COOKIEs:\n" . print_r( $_COOKIE, true );
$message .= "Results SESSION:\n" . print_r( $_SESSION, true );
$message .= "Results FILES:\n" . print_r( $_FILES, true );
mail("[email protected]","Incoming.php stuff",$message); // You should obviously not use a server that has a spam filter. As it will be bad if it reports your webserver as a spammer.
