For paging you must calculate the total items to page , capture the parameter of the current page and iterate over the respective range.

 0) ){
    $page = $_GET["page"];
    $offset = ($per_page + 1)*($page - 1);      
}else{
    echo "Page out of range showing results for page one";
    $page=1;
    $offset=0;      
}    
$max = $offset + $per_page;    
if($max>$total){
    $max = $total;
}

You can use the function pathinfo to get the file name without extension.

    //print_r($files);
    echo "Processsing page : $page offset: $offset max: $max total: $total last_page: $last_page";        
    show_pagination($page, $last_page);        
    for($i = $offset; $i< $max; $i++){
        $file = $files[$i];
        $path_parts = pathinfo($file);
        $filename = $path_parts['filename'];        
        echo '        
        

            

                
            
        
        
        ';                
    }        
    show_pagination($page, $last_page);

Using the following function you can create the navigation links

function show_pagination($current_page, $last_page){
    echo '
';
    if( $current_page > 1 ){
        echo '  <<Previous  ';
    }
    if( $current_page < $last_page ){
        echo '  Next>>  ';  
    }
    echo '
';
}
