$url = 'http://127.0.0.1' ;
$header = array("Host:127.0.0.1",
  "Content-Type:application/x-www-form-urlencoded",
  'Referer:http://127.0.0.1/toolindex.xhtml',
  'User-Agent: Mozilla/4.0 (compatible; MSIE .0; Windows NT 6.1; Trident/4.0; SLCC2;)');

$data = 'tools_id=1&env=gamma';
echo "argv:$data<br>";
$ret = curl_post($header, $data,$url);
$utf8 = iconv('GB2312', 'UTF-8//IGNORE', $ret);
echo 'return:<br>'.nl2br($utf8 ).'<br>';
