note 30288 added to language.variables.scope

regarding the above "unset" example: I quote from the manual page for "unset". "If a static variable is unset() inside of a function, unset() destroyes the variable and all its references. " As mentioned above, on this page, static vars are implemented as references. When you unset() a reference, what you are doing is deleting a particular name for that variable. In your example, you delete the LOCAL NAME $a, but the static contents are still there (hidden) and next time you call your function, a NEW LOCAL NAME (again $a...) is linked to the SAME backing data. Workaround would be something like "$a = null". unset($a) is very much like $a = &null however, which, if you read the notes above, won't have the desired affect on static or global variables. -- http://www.php.net/manual/en/language.variables.scope.php http://master.php.net/manage/user-notes.php?action=edit+30288 http://master.php.net/manage/user-notes.php?action=delete+30288 http://master.php.net/manage/user-notes.php?action=reject+30288
