how to make a basic paging of text files(no mysql used) in php?

for instance: i have this code here and a page will only display 5 text files only per page and there will be a  "next>>" button where in  , you can go to the other remaining text files and also there is the link "<<previous" where in, you can go back to the first five page you had started please help.

if($handle=@opendir($this->newsDir)){
	//Read all file form the actual directory
	while ($file=readdir($handle)){
		if(!is_dir($file)){
			$this->newsList[]=$file;
		}
	}
}
rsort($this->newsList);

/*Well, I will not use the function getNewsCount(){} anymore because i had a better idea of counting the number of news*/

I'll give you a quick example...

 

<?php

	$sort ( $this->newsList );
}


function displayNews ( $url, $directory, $maximum = 0, $sort = 'asort' )

	$this->getNewsList ( $directory, $sort );
