index.php to list all files in directory. just like apache did but it can be done in php built in server

index.php

<?php

$dir = __DIR__; // Directory where files are stored

if ($dir_list = opendir($dir))
{
	while($files[] = readdir($dir_list));
	sort($files);
	closedir($dir_list);
	foreach ($files as $file)
	{
		echo '<p><a href="'.$file.'">'.$file.'</a></p>';
	}
}
