sort array of arrays by number of elements in sub array

Vote count:

0

I have an array of arrays. I want to sort the containing array so that the sub arrays with the most elements in the array are first.

Example:

$my_array = array(
  array(0=>”a", 1=>”b”, 4=>”c"),
  array(3=>”z"),
  array(0=>”p”, 2=>”k"),
);

Desired result: The sub array with 3 elements is ordered 1st and the sub array with 1 element is ordered last.

$my_array = array(
  array(0=>”a", 1=>”b”, 4=>”c"),
  array(0=>”p”, 2=>”k"),
  array(3=>”z"),
);
