It seems the fix ( is not enough.

I'm tring to receive the response from, and the raw body is processed to gzuncompress instead gzinflate (because $zlibHeader[1] % 31 == 0).

I have found a solution at…

(ord($body[0]) == 0x78 && in_array(ord($body[1]), array(0x01, 0x5e, 0x9c, 0xda)) is false.

So, it should look like this:

<pre class="highlight">
if ($zlibHeader[1] % 31 == 0 && ord($body[0]) == 0x78 && in_array(ord($body[1]), array(0x01, 0x5e, 0x9c, 0xda)) {
    return gzuncompress($body);

return gzinflate($body);
