PHP array_chunk() — Split an Array into chunks. Chunks an array into arrays with size elements. The last chunk may contain less than size elements.

Syntax:

array_chunk ( array $array , int $size [, bool $preserve_keys = FALSE ] ) : array

Returns a multidimensional numerically indexed array, starting with zero, with each dimension containing size elements.
