note 86276 added to language.variables.superglobals

Tibor: It's not a good idea to use $_ENV unless you are specifying an environmental variable. This is probably a better example that I found on another page in php.net <?php function test() { $foo = "local variable"; echo '$foo in global scope: ' . $GLOBALS["foo"] . "\n"; echo '$foo in current scope: ' . $foo . "\n"; } $foo = "Example content"; test(); ?> ---- Server IP: 64.71.164.2 Probable Submitter: 130.207.66.123 ---- Manual Page -- http://www.php.net/manual/en/language.variables.superglobals.php Edit -- https://master.php.net/note/edit/86276 Del: integrated -- https://master.php.net/note/delete/86276/integrated Del: useless -- https://master.php.net/note/delete/86276/useless Del: bad code -- https://master.php.net/note/delete/86276/bad+code Del: spam -- https://master.php.net/note/delete/86276/spam Del: non-english -- https://master.php.net/note/delete/86276/non-english Del: in docs -- https://master.php.net/note/delete/86276/in+docs Del: other reasons-- https://master.php.net/note/delete/86276 Reject -- https://master.php.net/note/reject/86276 Search -- https://master.php.net/manage/user-notes.php
