利用Curl、socket、file_get_contents POST数据(转)

1.

<?php
/**
* Socket版本
* 使用方法：
* $post_string = "app=socket&amp;version=beta";
* request_by_socket('facebook.cn','/restServer.php',$post_string);
*/
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30){
$socket = fsockopen($remote_server,$port,$errno,$errstr,$timeout);
if (!$socket) die("$errstr($errno)");
fwrite($socket,"POST $remote_path HTTP/1.0");
fwrite($socket,"User-Agent: Socket Example");
fwrite($socket,"HOST: $remote_server");
fwrite($socket,"Content-type: application/x-www-form-urlencoded");
fwrite($socket,"Content-length: ".strlen($post_string)+8."");
fwrite($socket,"Accept:*/*");
fwrite($socket,"");
fwrite($socket,"mypost=$post_string");
fwrite($socket,"");
$header = "";
while ($str = trim(fgets($socket,4096))) {
$header.=$str;
}

$data = "";
while (!feof($socket)) {
$data .= fgets($socket,4096);
}
return $data;
