$options = Array ();
$options [' http '] [' method '] = $method;
$options [' http '] [' user_agent '] = $_server[' http_user_agent '];
$options [' http '] [' timeout '] = $timeout;
if ($method = = "POST"):
$length = strlen ($data);
$options [' http '] [' header '] = ' content-type:application/x-www-form-urlencoded\r\n '.
"Content-length: {$length}\r\n".
"P3p:cp=\" cura ADMa DEVa Psao psdo We bus UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP cor\ "\ r \ n".

"Connection:close\r\n";
$options [' http '] [' content '] = $data;
