如何用PHP定义socket的包头？

$info["path"] = '/index.html';
$info["host"] = '127.0.0.1';
$info["port"]=80;
$data_string= "name=peter";

这个是发送请求，重新定义了http头部，具体信息在函数里修改就可以了。

echo url_post($info, $data_string);

function url_post($info, $data_string){
$request = '';
$request.="POST ".$info["path"]." HTTP/1.1\n";
$request.="Host: ".$info["host"]."\n";
//$request.="Referer: $referrer\n";
//$request.="Content-type: application/x-www-form-urlencoded\n";
$request.="Content-length: ".strlen($data_string)."\n";
$request.="Connection: close\n";
$request.="\n";
$request.=$data_string."\n";

//echo $request;

$fp = fsockopen($info["host"],$info["port"]);
fputs($fp, $request);
$result = '';
while(!feof($fp)) {
$result .= fgets($fp, 128);
}
fclose($fp);

return $result;
}
