Bug #13280: suggestions about variables scope, warnning

From: Xuefer@21cn.com Operating system: any PHP version: 4.0.6 PHP Bug Type: Feature/Change Request Bug description: suggestions about variables scope, warnning suggestions 1. any variables start with $_ and $PHP_ and also $HTTP_ should be always global no need to use such as global $PHP_SELF; if possible, set_global_all(true); makes variables scope just like c/java do 2. if we access $PHP_POST_VARS['...'] and it's not set should trigger an special warnning, not a normal warnning cause it's not that variables we can initize so that, we can easily turn off the special warnning without ignoring the other normal warnning. 3. we don't like $a = 0; to initize an variable, we like int $a; // it's auto initized into 0 or int $a=1234; -- Edit bug report at: http://bugs.php.net/?id=13280&edit=1
