Bug #54440 libxml extension ignores default context
Submitted: 2011-04-01 11:43 UTC Modified: 2011-04-09 20:32 UTC
From: jpauli@php.net Assigned: cataphract
Status: Closed Package: Streams related
PHP Version: 5.3.6 OS: *nix
Private report: No CVE-ID:
 [2011-04-01 11:43 UTC] jpauli@php.net
Description:
------------
stream_context_set_default() doesn't publish the context to all PHP extension.

Example is ext/libxml that doesn't recognize the context.

Test script:
---------------
stream_context_set_default(array('http'=>array('proxy'=>'my_proxy_url')));

$x = simplexml_load_file('http://some_resource');

Expected result:
----------------
The resource gets loaded through the HTTP proxy

Actual result:
--------------
The resource is not loaded through the HTTP proxy.
For this to work, we have to use :

$ctx = stream_context_create(array('http'=>array('proxy'=>'my_proxy_url')));
libxml_set_streams_context($ctx); // userland manual bind

$x = simplexml_load_file('http://some_resource');
