Lars example also handles "." and ".." correctly. The example as given will skip an file whose first character is a "." ... so it doesn't count .htaccess, etc. etc.

I guess you would call it a feature or a bug depending on how you look at it given how ls works.

But I think I'd prefer to count them all!

The following gave me a faster result.

function count_files($dirname) {
if(is_dir($dirname))
$dir_handle = opendir($dirname);
if(!$dir_handle)
return false;

$files = 0;

while($file = readdir($dir_handle)) {
if($file != "." and $file != "..") {
if(!is_dir($dirname . "/" . $file))
$files++;
else
$files += count_files($dirname . "/" . $file);
}
}

closedir($dir_handle);

return $files;
}
