如何通过php使用xml/soap

[yjcool]

我把原文件贴出来吧，这样老是返回
400错误

最好有现成函数给个我

function post_xml_to_host($url, $data, $set_time_out=30)
{
$url = parse_url($url);
if (!$url) return "couldn't parse url";
if (!isset($url['port'])) { $url['port'] = ""; }
if (!isset($url['query'])) { $url['query'] = ""; }

$encoded = rawurlencode($data);
$fp = fsockopen($url['host'], $url['port'] ? $url['port'] : 80, &$errno, &$errstr, $set_time_out);
if (!$fp) return "Failed to open socket to $url[host]";
fputs($fp, sprintf("POST %s%s%s HTTP/1.1\n", $url['path'], $url['query'] ? "?" : "", $url['query']));
fputs($fp, "Content-type: text/xml; charset=GB2312\n");
fputs($fp, "Host: $url[host]\n");
fputs($fp, "Content-Length: " . strlen($encoded) . "\n");
fputs($fp, "Connection: Keep-Alive\n\n");
fputs($fp, "Data: $encoded\n");

$line = fgets($fp,1024);
if (!eregi("^HTTP/1\\.. 200", $line)) return 500;

$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;
}
