Description:
------------
We were testing a SOAP connection and kept receiving the following error:

 Error Fetching http body, No Content-Length, connection closed or chunked data.

After looking for this error message in PHP's source, I found get_http_body() was 
looking for headers with a space after the colon:

 header = get_http_header_value(headers, "Content-Length: ");

This trailing space is no longer required (yet a single space is recommended) by 
the HTTP 1.1 specification. (http://www.w3.org/Protocols/rfc2616/rfc2616-
sec4.html#sec4.2)

This issue should be easy to fix by removing the trailing space from the 12 or so 
calls to get_http_header_value().
