You'll need to read all of the files into an array, and then use array_slice to extract the correct 5 files based on the page number.

[printf]

I'll give you a quick example...

 

<?php

// news.php

/* beautified with active perl php cleaner 1.04 */

var $newsList = array ();

function getNewsList ( $directory, $sort )

	$this->newsList = array ();

	/* load the files from the directory */

	$files = glob ( $directory . '/*' );

	foreach ( $files AS $file )
	{
		if ( ! is_dir ( $file ) )
		{
			$this->newsList[] = $file;
		}
	}

	$sort ( $this->newsList );
}


function displayNews ( $url, $directory, $maximum = 0, $sort = 'asort' )
{
	$this->getNewsList ( $directory, $sort );

	$start     = 0;

	$nav       = false;

	$statisics = '';

	if ( $maximum > 0 )
	{
		$total = sizeof ( $this->newsList );

				$nav = true;

				if ( ! empty ( $_GET['s'] ) )

					$temp = intval ( $_GET['s'] );

					if ( $temp > 0  && $temp <= $total )
					{
						$start = $temp;
					}
				}
			}
		}

		$math = ( ( $start - 1 ) / $maximum ) + 1;

		$root = $maximum * $math;

		$next = $total < $root ? $total : $root;

		$this->newsList = array_slice ( $this->newsList, $start, $maximum, true );

	}
