从一个php文件向另一个地址post数据

可以使用以下函数来实现：
<?php
function posttohost($url, $data) {
$url = parse_url($url);
if (!$url) return "couldn't parse url";
if (!isset($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 "Failed to open socket to $url[host]";
fputs($fp, sprintf("post %s%s%s HTTP/1.0/n", $url['path'], $url['query'] ? "?" : "", $url['query']));
fputs($fp, "Host: $url[host]/n");
fputs($fp, "Content-type: application/x-www-form-urlencoded/n");
fputs($fp, "Content-length: " . strlen($encoded) . "/n");
fputs($fp, "Connection: close/n/n");
fputs($fp, "$encoded/n");
$line = fgets($fp,1024);
if (!eregi("^HTTP/1/.. 200", $line)) return;
$results = ""; $inheader = 1;
while(!feof($fp)) {
$line = fgets($fp,1024);
if ($inheader && ($line == "/n" || $line == "/r/n")) {
$inheader = 0;
}
elseif (!$inheader) {
$results .= $line;
}
}
fclose($fp);
return $results;
}
?>

也可以这样
<?php
$URL="www.mysite.com/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);
?>
