Post SOAP XML Request - php

Question

I was trying several examples from here, but nothing seems to work for me.
I need to send this envelope for the request:
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:v2="http://xmlns.oracle.com/oxp/service/v2">
<soapenv:Header />
<soapenv:Body>
<v2:runReport>
<v2:reportRequest>
<v2:attributeLocale>en-US</v2:attributeLocale>
<v2:attributeTemplate>Default</v2:attributeTemplate>
<v2:reportAbsolutePath>/Custom/Financials/Fac/XXIASA_FAC.xdo</v2:reportAbsolutePath>
<v2:dynamicDataSource xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
<v2:parameterNameValues xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
<v2:XDOPropertyList xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
</v2:reportRequest>
<v2:userID>user</v2:userID>
<v2:password>password</v2:password>
</v2:runReport>
</soapenv:Body>
</soapenv:Envelope>
This is my code:
$url = 'https://soapurl/v2/ReportService?WSDL';
$headers = array("Content-type: application/soap+xml; charset=\"utf-8\"", "Content-length: " . strlen($xml));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
print_r($response);
And this is the weird result I am getting back:
��R;o�0��+\ﱁTj�QZ�S_R���m�%sF�#��k�Q�l�����lwjT紅�$�H��Rñ���6OxW2gy�`�_aPƶ �|�\{��:Q��;�S���H���EG�<9���q$�v&gI�ҟ���l��6y��yB���?[��x���X5�a��6��5& ��<8�Q���e`�/F+������{���]������K�(2Q��T���X(�F*ϵ�k��eym����Ӊ��]�M�!y ��"m.�����0z�|�1���g�����}� ������C
Why I'm getting this?

Answer 1

If you used a network sniffer (I would recomend Wireshark), you would see that the data is compressed. This is usually employed server-side to reduce the bandwidth needed. Every single modern browser will decompress automatically, but curl on your application is not. If you saved that string on a file (response.bin, for example) and ran file response.bin, you will see the compressing algorithm employed (probably gzip or deflate).
To solve this, ask curl to decompress the response for you:
curl_setopt($ch,CURLOPT_ENCODING, '');
