PHP - 转到目录中的Next或Previous文件

Question

We're making a portfolio with pages in a directory like:

/portfolio/a-company-name.php  
/portfolio/another-company-name.php  
/portfolio/yet-another-company-name.php

We want to build "next" and "previous" links on each page, where people can navigate to the next or previous page in the directory. Any ideas?

I would think the only little snag might occur on the first and last files in the directory. So I guess there'd have to be an "if statement" of some sort to only build next/previous link if there's actually a next/previous file in the directory. Or, even better, to where it would just endlessly loop....for example if you were on the last file in the directory, and the "next" link would simply go to the first file.

Answer 1

There is this function scandir(). This will get all the files in a directory in an array. So you can loop through that or select the next file when you want too. Documentation:http://php.net/manual/en/function.scandir.php
