Note Submitter: electronerd@hotmail.com ---- If you are one of the many who think register_globals is the worst thing ever to happen to PHP, here is some code to clean your namespace. Put it at global scope, and it will obliterate any variables not in the safelist array. I have populated my array with the superglobals corresponding to the register_globals variables, so you can still access the data, but it poses much less of a threat. <?php $var_list = get_defined_vars(); $safelist = array('_GET', '_POST', '_COOKIE', '_SERVER', '_ENV', '_FILES', '_REQUEST'); foreach($var_list as $name => $value) { if(array_search($name, $safelist) === FALSE) { unset($$name); } } unset($var_list, $name, $value, $safelist); ?> If you empty the safelist, your namespace will be completely clean.
