This script will show you how to traverse the current directory so you can get information about it's files and directories.

Create an array with the file info

<?php
$pathStr = $_SERVER["DOCUMENT_ROOT"].$_SERVER["PHP_SELF"];
$dir = substr($pathStr, 0, strrpos($pathStr, "/")+1);
//HTTP_HOST
$dh = opendir($dir);
$aDirArr = array();
$aFileArr = array();
while (false !== ($filename = readdir($dh))) {
$pos = strrpos($filename, ".");
if ( ( is_dir($filename) && $filename != ".")
|| substr($filename, strrpos($filename, "."), strrpos($filename, ".")+3) == ".mp3"
|| substr($filename, strrpos($filename, "."), strrpos($filename, ".")+3) == ".gif"
|| substr($filename, strrpos($filename, "."), strrpos($filename, ".")+3) == ".jpg"
) {
$nFileKBsize = filesize($filename);
settype($nFileKBsize, "integer");
$nFileKBsize = $nFileKBsize/1024;
settype($nFileKBsize, "integer");
if(is_dir($filename)) {
$aDirArr[$filename] = array();
$aDirArr[$filename]['filename'] = $filename;
$aDirArr[$filename][] = "";
}
else {
$aFileArr[$filename] = array();
$aFileArr[$filename]['filename'] = $filename;
if(is_file($filename)) {
$aFileArr[$filename]['filesize'] = number_format($nFileKBsize)." KB";
}
else {
$aFileArr[$filename]['filesize'] = "";
}
}
}
}
?>

I'll show you how to generate the output on the next page.
