How to check if array like this

array(3) { [0]=> array(0) { } [1]=> array(0) { } [2]=> array(0) { } }

is actually empty ? Because for me this is an empty array but for the empty() this is an array with 3 elements and for count this is a array with length 3 .. so is there a way to do it without foreaching the array ?

Thank you in advance

  • Why don't you want to foreach() the array? Commented Feb 7, 2013 at 3:20

if(!array_filter($array)){
  // empty
}

+1 Clever. Note it will only work for two-dimensional arrays (like OP). Three dimensional arrays (array of arrays of arrays) would look something like array_walk($array, 'array_filter') && !array_filter($array) (untested)
That would be array_walk_recursive() (3D+)

It is also stated here

Check whether an array is empty

use array_filter();
