Here's an easy way to output the contents as a list of download links.
<?php
$count = 0;
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {$count++;
print("<a href=\"".$file."\">".$file."</a><br />\n");
}
}
echo '<br /><br /><a href="..">Return</a>';
closedir($handle);
}
?>
and simply use $count to list the overall number of files.
readdir
(PHP 4, PHP 5)
readdir — Read entry from directory handle
Description
string readdir
( resource $dir_handle
)
Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem.
Return Values
Returns the filename on success, or FALSE on failure.
Warning
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
Examples
Example#1 List all files in a directory
Please note the fashion in which readdir()'s return value is checked in the examples below. We are explicitly testing whether the return value is identical to (equal to and of the same type as--see Comparison Operators for more information) FALSE since otherwise, any directory entry whose name evaluates to FALSE will stop the loop (e.g. a directory named "0").
<?php
// Note that !== did not exist until 4.0.0-RC2
if ($handle = opendir('/path/to/files')) {
echo "Directory handle: $handle\n";
echo "Files:\n";
/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle))) {
echo "$file\n";
}
/* This is the WRONG way to loop over the directory. */
while ($file = readdir($handle)) {
echo "$file\n";
}
closedir($handle);
}
?>
Example#2 List all files in the current directory and strip out . and ..
<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>

Oops, made a few syntactical errors in the last example of getting only the final directory paths from a root dir. PHP 4 OO.
var $rootDir = '/SOME DIRECTORY';
print_r($this->getFinalDirs($this->rootDir));
function getFinalDirs($root)
{
return $this->getNext($root);
}
function getNext($path)
{
static $dirs = array();
$handle = opendir($path);
if($handle)
{
while (false!==($dir=readdir($handle)))
{
if ($dir!='.'&&$dir!='..'&& $dir!='.DS_Store')
{
if(is_dir($path.'/'.$dir))
{
$this->getNext($path.'/'.$dir);
} else
{
array_push($dirs, $path);
break;
}
}
}
}
return $dirs;
}

The following code is a bit nasty, it can be used to remove all files generated by apache.
You're not a root user on a system, but you sometimes need to remove all files generated by apache in a certain directory. You may use this after replacing 'bbs' at the bottom with 'directory' you want.
It tries to remove all files in a directory, but it can't unless it has an ownership. it doesn't check the ownership or permission.
<?php
function remove($dirname = '.')
{
if (is_dir($dirname))
{
echo "$dirname is a directory.<br />";
if ($handle = @opendir($dirname))
{
while (($file = readdir($handle)) !== false)
{
if ($file != "." && $file != "..")
{
echo "$file<br />";
$fullpath = $dirname . '/' . $file;
if (is_dir($fullpath))
{
remove($fullpath);
@rmdir($fullpath);
}
else
{
@unlink($fullpath);
}
}
}
closedir($handle);
}
}
}
remove('bbs');
?>

I haven't tested this yet, but it seems like it'll do just fine if you need files of a certain extension:
$dh = opendir($options['inputDir']);
$files = array();
while (($filename = readdir($dh)) !== false)
{
if (substr($filename, strrpos($filename, '.')) == $options['inputExt'])
{
$files[] = $filename;
}
}
closedir($dh);

PLease disregard my last two posts. For the last one, if you're looking for files with .php extension, you also get files with any extension that ends with 'p'. I wrote the function in quite a haste and now I am too busy to fix it - so don't use it! it's no good.

Sorry,
In my last post, if you only want to list files with certain extensions, then see how many letters this extension is, add one to it, and subtract it from the strlen of the file name. Review script below for details.

-------------------------------------------------------
If you want to list only a certain filetype, this case only jpg and gif files in an image directory
$dir = opendir ("../images");
while (false !== ($file = readdir($dir))) {
if (strpos($file, '.gif',1)||strpos($file, '.jpg',1) ) {
echo "$file <br />";
}
}
-----------------------------------------------------------------
This function would also echo files that have .gif or .jpg in their names such as myFile.gif.php (I don't know why I'd name a file like that, but I am just making a point, that's all folks!)
Perhaps a more exact way is to do the following:
...
while (false !== ($file = readdir($dir))) {
$lenOfFileName = strlen($file);
$extOffsetPos = $lenOfFileName - 5;
if (strpos($file, '.gif', $extOffsetPos) ||
strpos($file, '.jpg',$extOffsetPos) ) {
echo "$file <br />";
}
...
If your extensions are more than three letters, then increase the 5 to 6 (e.g. aspx) to 7 (e.g. php51) or whatever.

Here is an updated version of preg_find() [which has been linked from the glob() man page for years] - this function should provide most of what you want back from reading files, directories, different sorting methods, recursion, and perhaps most powerful of all the ability to pattern match with a PCRE regex.
You can get preg_find here: http://www.pgregg.com/projects/php/preg_find/preg_find.php.txt
or if you prefer colourful .phps format: http://www.pgregg.com/projects/php/preg_find/preg_find.phps
or scoll down to the end of this note.
I wrote several examples on how to use it on my blog at: http://www.pgregg.com/forums/viewtopic.php?tid=73
simple glob() type replacement:
$files = preg_find('/./', $dir);
recursive?
$files = preg_find('/./', $dir, PREG_FIND_RECURSIVE);
pattern match? find all .php files:
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE);
sorted alphabetically?
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE|PREG_FIND_SORTKEYS);
sorted in by filesize, in descending order?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTFILESIZE|PREG_FIND_SORTDESC);
$files=array_keys($files);
sorted by date modified?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTMODIFIED);
$files=array_keys($files);

It should work, but it'll be better to read section 13.1.3 Cache-control Mechanisms of RFC 2616 available at http://rfc.net/rfc2616.html before you start with confusing proxies on the way from you and the client.
Reading it is the best way to learn how proxies work, what should you do to modify cache-related headers of your documents and what you should never do again. :-)
And of course not reading RFCs is the best way to never learn how internet works and the best way to behave like Microsoft corp.
Have a nice day!

Someone mentioned the infinite recursion when a symbolic link was found...
tip: is_link() is a nice function :)
