How do I split a large array into smaller sub-arrays?

[codebeacon]

Hi,

I was wondering how I could split a large array into smaller chunks?

For example:

arr = ["hello", "my", "name", "is", "name", "hello", "my", "name", "is", "name2", "hello", "my", "name", "is", "name3"]

And I want to split the array into:

arr2 = [["hello", "my", "name", "is", "name"], ["hello", "my", "name", "is", "name2"], "hello", "my", "name", "is", "name3"]

If someone could please help, I would gladly appreciate it.
Thanks!
