可以使用以下函数来实现：

<?php
functionposttohost($url,$data){
$url=parse_url($url);
if(!$url)return"couldn'tparseurl";
if(!isset($url['port'])){$url['port']="";}
if(!isset($url['query'])){$url['query']="";}

$encoded="";

while(list($k,$v)=each($data)){
$encoded.=($encoded?"&":"");
$encoded.=rawurlencode($k)."=".rawurlencode($v);
}

$fp=fsockopen($url['host'],$url['port']?$url['port']:80);
if(!$fp)return"Failedtoopensocketto$url[host]";

fputs($fp,sprintf("POST%s%s%sHTTP/1.0\n",$url['path'],$url['query']?"?":"",$url['query']));
fputs($fp,"Host:$url[host]\n");
fputs($fp,"Content-type:application/x-/test.php";
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,"https://$URL");
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,"Data1=blah&Data2=blah");
curl_exec($ch);
curl_close($ch);
?>
