Test str_split() function : usage variations - different heredoc strings as 'str' argument

specified, break the string down into chunks each
split_length characters long.
* Source code: ext/standard/string.c
* Alias to functions: none

* Passing different heredoc strings as 'str' argument to the str_split()
