PHP - Compressed Payload

I have a web service that queries an Oracle database and then returns a struct.
If there is any error on my side, I still reply the struct, except it is populated with differnt values.
If I change the coding in my error handling to return the struct populated with the error values, then it returns fine,
but if I simulate an ORACLE error (use the incorrect passoword for example) I get the following error:
"XML error parsing SOAP payload on line 2: Invalid document end"

Any suggestions?
Is there a way that I can display the "SOAP Payload" to see what is missing?
The following extract from my code:

I am being sent an XML feed which needs to be downloaded in a 'compressed way'. The example I have been given is this:   $url = 'http://myurl.com';
$headers[] = "Accept-Encoding: gzip,deflate";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$data = curl_exec($ch);   but the output I am getting is jargon like this with loads of black diamond question marks:�   +T��sƒ���-}#v���]K���������HB�$&G�����Y�����'߷s�,�.4֫'?'���9;*9^��>�j~�ǫ}z|hq�J��Գ".o2)~b​���U~I|   How to a convert it back into XML? Many thanks

Is there a way I can readily stream-process a compressed XML file in PHP?  Something like this NON WORKING example:
Code: [Select]
$reader = new XMLReader();
$reader->open(bzopen($planet_file,"r"));
while ($reader->read()) {
