Description:
------------
readfile() problem(stream used)
stream functions do not support HTTP 1.1 206 Partial Content.


Reproduce code:
---------------
$context=array('http' => array ('header'=> 'Range: bytes=1024-', ),);
$xcontext = stream_context_create($context);
readfile('http://localhost/1.mp3',0,$xcontext);
//the file is exist,if I don't use $xcontext,the code works well.

Expected result:
----------------
I want to get the Partial Content from 1024 byte to the end of the file
It says:
[function.readfile]: failed to open stream: HTTP request failed! HTTP/1.1 206 Partial Content
