php how to go one level up on dirname(FILE)

php dirname

For PHP < 5.3 use:

$upOne = realpath(dirname(__FILE__) . '/..');

In PHP 5.3 to 5.6 use:

$upOne = realpath(__DIR__ . '/..');

In PHP >= 7.0 use:

$upOne = dirname(__DIR__, 1);

php dirname

If you happen to have php 7.0+ you could use levels.

dirname( __FILE__, 2 ) with the second parameter you can define the amount of levels you want to go back.

php dirname

Try this

dirname(dirname( __ FILE__))

Edit: removed "./" because it isn't correct syntax. Without it, it works perfectly.
