我是靠谱客的博主苹果音响，最近开发中收集的这篇文章主要介绍PHP的chunk_split() 函数把字符串分割为一连串更小的部分，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

chunk_split() 函数把字符串分割为一连串更小的部分。
chunk_split(string,length,end)

string	必需。规定要分割的字符串。
length	可选。数字值，定义字符串块的长度。默认是 76。
end	可选。字符串值，定义在每个字符串块末端放置的内容。默认是 rn。

<?php
echo chunk_split("Shanghai",2,".");
Sh.an.gh.ai.
