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();
?>
