Thanks for reply, but I want to:
unset($ARR['a']['b'])
Imagine I have this:
$KEYS = array('a', 'b', 'c');
And I want to:
unset($ARR['a']['b']['c'])
It's probably impossible, unless I do something dirty like this:
list($rootA, $rootB, $rootC) = $KEYS;
if (isset($rootC)) unset($x[$rootA][$rootB][$rootC]);
elseif (isset($rootB)) unset($x[$rootA][$rootB]);
elseif (isset($rootA)) unset($x[$rootA]);
