How to subdivide an array into the same number of elements?

Question

PHP

The task is simple, but I just can't process it all and come up with something.
In general, there is an array of paragraphs (roughly speaking) in it an array of lines. And so, it is necessary to enclose each 5 lines in a separate array.
Initially, the array is:
array(
[0]=>value
[1]=>value
...
[n]=>value
)
Should be turned into:
array(
[0]=> array(
[1]=>value
[2] =>value
[n]=>value
)
[1]=> array(...)
...
[n]=> array(...)
)

Answer 1

$arrays = array_chunk($array, $n);
