Answer 1

readdir() always return "." & "..". So you just have to validate and skip them as shown in the example #2 of the manual

<?php
if ($handle = opendir('.')) {
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
            echo "$entry
";
        }
    }
    closedir($handle);
}
?>

Resulting in

[...]
        if ($handle = opendir($log_directory))
        {
                while(($file = readdir($handle)) !== FALSE)
                {
                    if ($file != "." && $file != "..") {
                        $results_array[] = $file;
                    }
                }
                closedir($handle);
        }
