Bug description: Duplicate \r\n after HTTP headers when "header" context
option is an array.
Description:
------------
When making an HTTP request through the HTTP stream wrapper, there will
be a duplicate \r\n sequence separating header lines and request body if
the HTTP stream context option "header" is an array (which is possible
since 5.2.10; it had to be a string with the individual, \r\n-separated
header lines before that).
As a result, the last two bytes of the request will never reach the
destination server, as it closes the connection when reaching the
indicated Content-Length (which is off by two bytes due to the extra
\r\n). The HTTP specification explicitly states that one \r\n sequence
should be used to separate the last (\r\n-terminated) header line from
the request body.
All is fine when supplying headers as a string instead of an array.
Reproduce code:
---------------
$context = stream_context_create(array('http' => array('header' =>
array('X-Foo: bar', 'Content-Type: text/plain'), 'method' => 'POST',
'content' => 'ohai')));
$fd = fopen('http://127.0.0.1:12342/', 'rb', false, $context);
Expected result:
----------------
A \r\n after the last header, another \r\n to create a blank line, then
"ohai"
Actual result:
--------------
A \r\n after the last header, then \r\n twice which creates two blank
lines, then "oh". "ai" never arrives as the Content-Length is reached.
