note 84720 added to function.unset

According to the Manual: If you would like to unset() a global variable inside of a function, you can use the $GLOBALS array. But the results, as tested below, are surprising. <?php $weekdays = array('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'); function destroy_a_global() { unset($_GLOBALS['weekdays']); print "++++++ weekdays inside of function" . PHP_EOL; print_r($weekdays); // it's gone print "++++++ _GLOBALS['weekdays'] inside of function" . PHP_EOL; print_r($_GLOBALS['weekdays']); // it's gone } destroy_a_global(); print "++++++ weekdays outside of function" . PHP_EOL; print_r($weekdays); // it's back print "++++++ _GLOBALS['weekdays'] outside of function" . PHP_EOL; print_r($_GLOBALS['weekdays']); // it's gone ?> ---- Server IP: 64.71.164.2 Probable Submitter: 84.44.226.119 ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- https://master.php.net/note/edit/84720 Del: integrated -- https://master.php.net/note/delete/84720/integrated Del: useless -- https://master.php.net/note/delete/84720/useless Del: bad code -- https://master.php.net/note/delete/84720/bad+code Del: spam -- https://master.php.net/note/delete/84720/spam Del: non-english -- https://master.php.net/note/delete/84720/non-english Del: in docs -- https://master.php.net/note/delete/84720/in+docs Del: other reasons-- https://master.php.net/note/delete/84720 Reject -- https://master.php.net/note/reject/84720 Search -- https://master.php.net/manage/user-notes.php
