What is the interface?
------ Solution --------------------
This is data submission. the call is simple. you can directly use fso_get_contents and then analyze the xml.
$ Url = "https://xxx.com/xml ";

$ Ch = curl_init ($ url );
$ Headers = array (
"POST". $ url. "HTTP/1.0 ",
"Content-type: text/xml; charset = \" UTF-8 \"",
"Accept: text/xml ",
"Content-length:". strlen ($ xmlcontent ),
);
$ Ch = curl_init ();
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
Curl_setopt ($ ch, CURLOPT_TIMEOUT, 60 );
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers );
Curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, 0 );

// Apply the XML to our curl call
Curl_setopt ($ ch, CURLOPT_POST, 1 );
Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ xmlcontent );

$ Data = curl_exec ($ ch );
If (curl_errno ($ ch )){
Die ('meeting information error. it is possible that the meeting has not started yet! ');
Exit;
} Else {
// Show me the result
// Var_dump ($ data );
Curl_close ($ ch );
}
