Description:
------------
hi;

It seems that the Context option 'content' of HTTP wrapper for stream, does not pass the value to the server.

Reproduce code:
---------------
// === client side php code === 

$opts = array('http'=>array('method'=> "POST",
                            'content' => 'foo=bar'));

$context = stream_context_create($opts);

echo file_get_contents ($url, false, $context);




// === server side php code ===
print $_POST['foo'];


Expected result:
----------------
bar
