<?php
// Create a global variable that keeps the good/bad status of this script
// Preset it to 'false'.  Assume the worst case unless we say otherwise.
$status = false;

// Now create a shutdown function that just outputs a simple status message
function my_shutdown() {
	// Output either OK or ERROR, depending upon the status
	echo $GLOBALS['status'] ? 'OK' : 'ERROR';
}

// Register this as a shutdown function:
register_shutdown_function('my_shutdown');

// Now that we are completely setup, also ensure no errors are displayed
ini_set('display_errors', false);

// Let's attempt to save any data sent to us to a file:
if (!(file_put_contents('saved.txt', serialize($_REQUEST)))) {
	// We had an error, just exit
	exit();
}

// If we made it here, we are done, just set the status to true, meaning we
// are exiting cleanly.
$status = true;
