php有三种方法可以post数据,分别为Curl、socket、file_get_contents:

请看下边的代码：

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 $remote_path HTTP/1.0\r\n");
fwrite($socket,"User-Agent: Socket Example\r\n");
fwrite($socket,"HOST: $remote_server\r\n");
fwrite($socket,"Content-type: application/x-www-form-urlencoded\r\n");
fwrite($socket,"Content-length: ".strlen($post_string)+8."\r\n");
fwrite($socket,"Accept:*
function request_by_curl($remote_server,$post_string){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$remote_server);
curl_setopt($ch,CURLOPT_POSTFIELDS,'mypost='.$post_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_USERAGENT,"Jimmy's CURL Example beta");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}

function request_by_other($remote_server,$post_string){
$context = array(
'http'=>array(
‘method’=>’POST’,
‘header’=>’Content-type: application/x-www-form-urlencoded’.”\r\n”.
‘User-Agent : Jimmy\’s POST Example beta’.”\r\n”.
‘Content-length: ‘.strlen($post_string)+8,
‘content’=>’mypost=’.$post_string)
);
$stream_context = stream_context_create($context);
$data = file_get_contents($remote_server,FALSE,$stream_context);
return $data;
}
