PHP list all files in directory

In any directory there are many files and directories. In order to show them we use opendir() function. Consider the following example :

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

Following output will be produced :
