[PHP] POST/GET using a proxy server

[David Yee]

Hi all- how do I modify the following function to work over a proxy server?
Thanks for any help.

David


/* sendToHost
 * ~~
 * Params:
 *   $host  - Just the hostname.  No http:// or
  /path/to/file.html portions
 *   $method- get or post, case-insensitive
 *   $path  - The /path/to/file.html part
 *   $data  - The query string, without initial question mark
 *   $useragent - If true, 'MSIE' will be sent as
  the User-Agent (optional)
 *
 * Examples:
 *   sendToHost('www.google.com','get','/search','q=php_imlib');
 *   sendToHost('www.example.com','post','/some_script.cgi',
 *  'param=First+Paramsecond=Second+param');
 */

function sendToHost($host,$method,$path,$data,$useragent=0)
{
// Supply a default method of GET if the one passed was empty
if (empty($method)) {
$method = 'GET';
}
$method = strtoupper($method);
$fp = fsockopen($host, 80);
if ($method == 'GET') {
  $path .= '?' . $data;
}
fputs($fp, $method $path HTTP/1.1\r\n);
fputs($fp, Host: $host\r\n);
if ($useragent) {
  fputs($fp, User-Agent: MSIE\r\n);
}
if ($method == 'POST') {
  fputs($fp,Content-type: application/x-www-form-urlencoded\r\n);
  fputs($fp, Content-length:  . strlen($data) . \r\n);
}
fputs($fp, Connection: close\r\n\r\n);
if ($method == 'POST') {
fputs($fp, $data);
}

while (!feof($fp)) {
$buf .= fgets($fp,128);
}
fclose($fp);
return $buf;
}

Something like so:

/* sendToHost
 * ~~
 * Params:
 *   $proxy - Proxy you want to use
 *   $host  - Just the hostname.  No http:// or
  /path/to/file.html portions
 *   $method- get or post, case-insensitive
 *   $path  - The /path/to/file.html part
 *   $data  - The query string, without initial question mark
 *   $useragent - If true, 'MSIE' will be sent as
  the User-Agent (optional)
 *
 * Examples:
 *   sendToHost('webcache', 'www.google.com','get','/search','q=php_imlib');
 *   sendToHost('localhost', 'www.example.com','post','/some_script.cgi',
 *  'param=First+Paramsecond=Second+param');
 */

function sendToHost($proxy, $host,$method,$path,$data,$useragent=0)
{
// Supply a default method of GET if the one passed was empty
if (empty($method)) {
$method = 'GET';
}
$method = strtoupper($method);
$fp = fsockopen($proxy, 8080);
if ($method == 'GET') {
  $path .= '?' . $data;
}
fputs($fp, $method http://$host/$path HTTP/1.0\r\n);
fputs($fp, Host: $host\r\n);
if ($useragent) {
  fputs($fp, User-Agent: MSIE\r\n);
}
if ($method == 'POST') {
  fputs($fp,Content-type: application/x-www-form-urlencoded\r\n);
  fputs($fp, Content-length:  . strlen($data) . \r\n);
}
fputs($fp, Connection: close\r\n\r\n);
if ($method == 'POST') {
fputs($fp, $data);
}

while (!feof($fp)) {
$buf .= fgets($fp,128);
}
fclose($fp);
return $buf;
}

I've not tried this code, but I think I got it right :)
Also please note that this connects to proxys on port 8080, you might need
to change that.
Oh and I changed the http/1.1 to 1.0 because I find it has less problems :)

Hope this works/helps
