Did you try my solution? It should be alot quicker than the above
method, but I did forget to ask, are their directories in the folder
that shouldnt be counted?

Thats a problem with the above example by thib also, file names without
extensions wouldnt be counted.

A sure fire way of doing it would be:

<?php
$dir = './directory';
function countfiles($dir = '.')
{
$count = 0;
$dir = rtrim($dir,'/').'/';
if(!is_dir($dir)) return false;
foreach(new DirectoryIterator($dir) as $file)
{
if(is_file($dir.$file)) $count++;
}
return $count;
}
echo countfiles();
?>

Of course, this is PHP5, and if you dont have PHP5, you should be
changing hosts :P Use these new SPL functions given to us for faster code!
