How to check if a multi-dimensional array only contains empty values?

Question

I looked around and can\'t quite find the answer for this, so I\'m wondering if I contain an array such as this..

$array[\'foo\'][\'bar\'][1] = \'\';
$array[\'fo

$array['foo']['bar'] isn't empty because it's actually array(1=>'',2=>'',3=>'',4=>'').

You would need to do a foreach loop on it to check if it is indeed all empty.

$arr_empty = true;
foreach ($array['foo']['bar'] as $arr) {
    if (!empty($arr)) {
        $arr_empty = false;
    }
}
//$arr_empty is now true or false based on $array['foo']['bar']
