Question

I have this multidimensional array:

Array
(
    [0] => Array
        (
        [0] => 2012-02-26 07:15:00
        )
    [1] => Array
        (
              


        

Answer 1

$sizes=array();
foreach ($myarray as $k=>$v) 
  if (!is_array($v)) $sizes["$k"]=0;
  else $sizes["$k"]=sizeof($v);

sort($sizes);


echo array_pop($sizes); //outputs 3
echo array_pop($sizes); //outputs 2
echo array_pop($sizes); //outputs 2
