Read the PHP Manual on arrays.

Just set your image icon array to use keys that relate to the file extension you have found in your directory reading script!

simple example...


$icons = array ( 
	'gif' => array ( 'gif.gif', 'image/gif' ), 
	'doc' => array ( 'msdoc.gif', 'application/msword' ), 
	'unknown' => array ( 'ostrm.gif', 'application/octet-stream' ) 
);

while(reading_directory)
{
	$ext = substr ( $file, ( strrpos ( $file, '.' ) + 1 ) );

$info = stat ();

if ( ! isset ( $icons[$ext] ) )
{
	$ext = 'unknown';

}

// build the directory array for the display, makes sorting easy! -> array_multisort();

$files[] = array ( 
	'name' => $file, 
	'path' => $dir . '/' . $file, 
	'size' => $info[7], 
	'date' => date ( 'r', $info[9] ), 
	'icon' => $icons[$ext][0], 
	'type' => $icons[$ext][1]
	);

} // end while read dir

clearstatcache ();
