Costs in PHP, Is it worth it to read an XML than to list files in a folder?
<p>I'll try to explain myself . I want to show a list of files from a folder in a web using PHP and what I want know is what is better in time and server costs (server requests and data transmissions ) , </p>

<p>Read an XML with the list of files in it or open the folder and see the files one bye one?</p>

<p>P.D: The list must contain from 100 to 200 files in it.</p>
