fsockopen: fetching url

[branimir.topic@xxxxxxxxxxxxxxxxxxx]

I'm using code below to fetch content from the url.
This code was worked properly on two servers I tested but it want worked on
the
designated one,  so after getting error message I figure it out it may
be php.ini settings limitation
----------------------------------------------------------------------------------------------------------------
"The server encountered an internal error or misconfiguration and was
unable to complete your request."
"Additionally, a 404 Not Found error was encountered while trying to use an
ErrorDocument to handle the request."
----------------------------------------------------------------------------------------------------------------


So here's the settings I found as possible reason for limitation on code
execution.
----------------------------------------------------------------------------------------------------------------
disable_functions: readfile, system, passthru, shell_exec, shell_exec,
system, execreadfile, system, passthru, shell_exec, shell_exec, system,
exec
----------------------------------------------------------------------------------------------------------------
Does anybody hava any tip how to workarround on this?


CODE
----------------------------------------------------------------------------------------------------------------
function fetchURL( $url ) {
   $url_parsed = parse_url($url);
   $host = isset($url_parsed["host"]) ? $url_parsed["host"]: "";
   $port = isset($url_parsed["port"]) ? $url_parsed["port"]: 0;
   if ($port==0)
       $port = 80;
   $path = $url_parsed["path"];

   $query = isset($url_parsed["query"]) ? $url_parsed["query"]: "";

   if ($query != "")
       $path .= "?" . $query;

   $out = "GET $path HTTP/1.0\r\nHost: $host\r\n\r\n";

   $fp = fsockopen($host, $port, $errno, $errstr, 30);

   fwrite($fp, $out);
   $body = false;
   $in = "";
   while (!feof($fp)) {
       $s = fgets($fp, 1024);
       if ( $body )
           $in .= $s;
       if ( $s == "\r\n" )
           $body = true;
   }

   fclose($fp);

   return $in;
}
