Given a string and we have to split a fixed number of characters from the string.
给定一个字符串，我们必须从该字符串中拆分固定数量的字符。
When we need a set of small parts of the string (of a fixed number of characters), we can use chunk_split() function. It returns a defined number of characters from the string and can also add a character or string after the string.
