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         


        

Answer 1

A short alternative would be:

if (empty(implode($array['foo']['bar']))) {
  // is empty
}

Note that some single values may be considered as empty. See empty().
