Laragon - index.php personalized

<?php

# Directory Index (dirindex.php)
#
# Reads the current directory's content and displays it as
# HTML.  Useful if file listing is denied by the web server
# configuration.
#
# Installation:
# - Put in any directory you like on your PHP-capable webspace.
# - Rename to 'index.php' if you like it to get called if no
#   file is specified in the URL (e.g. www.example.com/files/).
# - Fit the design to your needs just using HTML and CSS.
#
# Changes since original release (25-Mar-2002):
# - simplified and modernized markup and styles (HTML5, CSS3,
#   list instead of table)
# - more functional programming approach
# - improved configurability
# - escaping of HTML characters
# - license changed from GPL to MIT
# - requires PHP 5.3.0 or later
