php接受xml和发送(post)xml
接收xml:
$xml = file_get_contents('php://input');
发送(post):
$xml_data = <xml>…</xml>";
$url = http://dest_url;
$header[] = "Content-type: text/xml";//定义content-type为xml
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);
$response = curl_exec($ch);
if(curl_errno($ch))
{
print curl_error($ch);
}
curl_close($ch);
$url = http://dest_url;
$header[] = "Content-type: text/xml";//定义content-type为xml
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);
