$param = array(
    'name' => 'ken',
    'gender' => 'man'

$url = $url.'?'.http_build_query($param);
 
// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);
 
if(!$fp){
    return false;
}
 
// send request
$out = "GET ${url} HTTP/1.1\r\n";
$out .= "Host: ${host}\r\n";
$out .= "Connection:close\r\n\r\n";
 
fputs($fp, $out);
 
// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}
 
fclose($fp);
 
$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);
