Note: Underlying socket stream context options
Additional context options may be supported by the underlying transport For http:// streams, refer to context options for the tcp:// transport. For https:// streams, refer to context options for the ssl:// transport.
Note: HTTP status line
When this stream wrapper follows a redirect, the wrapper_data returned by stream_get_meta_data() might not necessarily contain the HTTP status line that actually applies to the content data at index 0.The first request returned a 301 (permanent redirect), so the stream wrapper automatically followed the redirect to get a 200 response (index = 4).array ( 'wrapper_data' => array ( 0 => 'HTTP/1.0 301 Moved Permantenly', 1 => 'Cache-Control: no-cache', 2 => 'Connection: close', 3 => 'Location: http://example.com/foo.jpg', 4 => 'HTTP/1.1 200 OK', ...
