Using Curl and Ajax to Proxy Flash

Most of the time Htaccess and Apache can handle proxies like this much easier, but just in case you need to do this, here is the code for a PHP proxy from http://developer.yahoo.com/javascript/samples/proxy/php_proxy_simple.txt

<?php
// PHP Proxy example for Yahoo! Web services. 
// Responds to both HTTP GET and POST requests
//
// Author: Jason Levitt
// December 7th, 2005
//

// Allowed hostname (api.local and api.travel are also possible here)
define ('HOSTNAME', 'http://search.yahooapis.com/');

// Get the REST call path from the AJAX application
// Is it a POST or a GET?
$path = ($_POST['yws_path']) ? $_POST['yws_path'] : $_GET['yws_path'];
$url = HOSTNAME.$path;

// Open the Curl session
$session = curl_init($url);

// If it's a POST, put the POST data in the body
if ($_POST['yws_path']) {
	$postvars = '';
	while ($element = current($_POST)) {
		$postvars .= key($_POST).'='.$element.'&';
		next($_POST);
	}
	curl_setopt ($session, CURLOPT_POST, true);
	curl_setopt ($session, CURLOPT_POSTFIELDS, $postvars);
}

// Don't return HTTP headers. Do return the contents of the call
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// Make the call
$xml = curl_exec($session);

// The web service returns XML. Set the Content-Type appropriately
header("Content-Type: text/xml");

echo $xml;
curl_close($session);

?>

This script will login to google reader with the $username and 
$password variables and fetch the number of subscribers for 
the $feedurl variable that you specify.
