Also noted that good coding practice means you should never see this. Addresses Bug #45283. Also fixed some minor grammatical problems. ------------------------------------------------------------------------ [2008-11-08 01:37:37] jani@php.net Why this needs documenting: 1. It's not a bug. 2. Changing this would break BC. 3. register_globals is off by default 4. register_globals will be gone in next major version. ------------------------------------------------------------------------ [2008-11-05 19:55:34] php at info-svc dot com On the other hand, if register_globals is broken then extract($_FILES, EXTR_SKIP); is working as intended, skipping keys already registered. I can understand it's either a bug or a documentation problem, but something isn't right here. ------------------------------------------------------------------------ [2008-11-05 11:15:22] vrana@php.net Results of extract() shouldn't depend on register_globals. ------------------------------------------------------------------------ [2008-07-02 12:26:50] jani@php.net It's documentation issue. Plus you really should NOT be using register_globals=On. And using extract() on $_FILES...well..that's very flaky idea to begin with. Just don't do it. :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
