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;
 }?>
