note 66708 added to language.variables.scope

When I first was writing my last comment, I was thinking that somehow there was a php bug causing two separate global namespaces. As I was composing the post I realized that perhaps the problem was unsetting the variable, and removed all my references to two namespaces. Now in reviewing some of the posts below which discuss the issue of unsetting global variables as an issue, I think that the unsetting is the problem, and that the preferred method is not to unset them but assign null to them. ---- Server IP: 216.194.113.175 Probable Submitter: 69.23.252.228 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- http://master.php.net/note/edit/66708 Del: integrated -- http://master.php.net/note/delete/66708/integrated Del: useless -- http://master.php.net/note/delete/66708/useless Del: bad code -- http://master.php.net/note/delete/66708/bad+code Del: spam -- http://master.php.net/note/delete/66708/spam Del: non-english -- http://master.php.net/note/delete/66708/non-english Del: in docs -- http://master.php.net/note/delete/66708/in+docs Del: other reasons-- http://master.php.net/note/delete/66708 Reject -- http://master.php.net/note/reject/66708 Search -- http://master.php.net/manage/user-notes.php
