this function should give you a starting point
it will fetch any http url with the specified referrer
handling the query parms should be pretty trivial, so i will leave that part for you to do
<?php
echo geturl('http://some-url', 'http://referring-url');
function geturl($url, $referer) {
$headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg,text/html,application/xhtml+xml';
$headers[] = 'Connection: Keep-Alive';
$headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';
$useragent="Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)";
$process = curl_init($url);
curl_setopt($process, CURLOPT_HTTPHEADER, $headers);
curl_setopt($process, CURLOPT_HEADER, 0);
curl_setopt($process, CURLOPT_USERAGENT, $useragent);
curl_setopt($process, CURLOPT_REFERER, $referer);
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1);
$return = curl_exec($process);
curl_close($process);
return $return;
}
?>
