Description:
------------
Hi,

the HttpRequest::getHeaders() method returns an associative array, which cannot be accessed normally. See code sample.

The php -i output for pecl_http:


HTTP Support => enabled
Extension Version => 1.7.1
Registered Classes => HttpUtil, HttpMessage, HttpRequest, HttpRequestPool, HttpRequestDataShare, HttpDeflateStream, HttpInflateStream, HttpResponse, HttpQueryString
Output Handlers => ob_deflatehandler, ob_inflatehandler, ob_etaghandler
Stream Filters => http.chunked_decode, http.chunked_encode, http.deflate, http.inflate

Used Library => Compiled => Linked
libcurl => 7.21.3 => 7.21.3
libevent => 1.4 or greater => 1.4.12-stable
libz => 1.2.3.4 => 1.2.3.4
libmagic => disabled => disabled


Test script:
---------------
/* @var $req \HttpRequest */
$headers = (array)$req->getHeaders();
var_export($headers['Accept']); // Undefined index: Accept
array_key_exists('Accept', $headers); // false
$headers = unserialize(serialize($headers));
array_key_exists('Accept', $headers); // true

Expected result:
----------------
Script should display the contents of Accept header
e.g. array(0 => 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8')
first array_key_exists should yield true

Actual result:
--------------
Undefined index: Accept
false
