Sorting array based on array length [duplicate]

Question

What's the best way in PHP to sort an array of arrays based on array length?

array (size=3)
   0 => 
      array (size=3)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)
   1 => 
      array (size=6)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)
         3 => string '4' (length=1)
         4 => string '5' (length=1)
         5 => string '6' (length=1)
   2 => 
      array (size=4)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)
         3 => string '4' (length=1)

I need sorting it based of size of array Become like this:

array (size=3)
   0 => 
      array (size=6)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)
         3 => string '4' (length=1)
         4 => string '5' (length=1)
         5 => string '6' (length=1)
   1 =>     
      array (size=4)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)
         3 => string '4' (length=1)
   2 => 
      array (size=3)
         0 => string '1' (length=1)
         1 => string '2' (length=1)
         2 => string '3' (length=1)

The best way is to use usort

you should use usort.

function cmp($a, $b){
    return (count($b) - count($a));
}
usort($array, 'cmp'); //$array is your array 
$arrayAfterSort = $array;
