PHP ini_get

A somewhat useful function in PHP - ini_get(string $varname). Useful for troubleshooting, would have come in handy for me once or twice in the past when trying to prove to a server admin that globals were on or off. IE:

echo 'register_globals = ' . ini_get('register_globals') . "\n";

Returns something like:

register_globals = 0
