导读：php下POST报文到主机，post提交利用代码

<?
/*
** POST报文到主机
*/
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);
}

$port = $url['port'] ? $url['port'] : 80;
$fp = fsockopen($url['host'], $port, $errno, $errstr);
if (!$fp) return "Failed to open socket to $url[host] $port ERROR: $errno - $errstr";

fputs($fp, sprintf("POST %s%s%s HTTP/1.0n", $url['path'], $url['query'] ? "?" : "", $url['query']));
fputs($fp, "Host: $url[host]n");
fputs($fp, "Content-type: application/x-www-form-urlencodedn");
fputs($fp, "Content-length: " . strlen($encoded) . "n");
fputs($fp, "Connection: closenn");

fputs($fp, "$encodedn");

$line = fgets($fp,1024);
if (!eregi("^HTTP/1.. 200", $line)) return;

$results = ""; $inheader = 1;
while(!feof($fp)) {
$line = fgets($fp,1024);
if ($inheader && ($line == "n" || $line == "rn")) {
$inheader = 0;
}
elseif (!$inheader) {
$results .= $line;
}
}
fclose($fp);

return $results;
}/* end function PostToHost */
?>
