Sorting directory (readdir)

[Anon]

<?php
$handle=opendir('.');
while (false!=($file = readdir($handle)))
{
if ($file != "." && $file != ".." && ereg(".xml",$file))
{
$file_array[$file]= fileatime($file); //STORING
}
}
closedir($handle);
arsort($file_array, SORT_NUMERIC); //sort file array based on timestamp in descending order.
reset($file_array);
$i =0;
foreach($file_array,$item)
{
if($i < 20)
print $item;
$i++;
}
?>

thanx

So what's the problem?

When I try to load the page, it doesn't load and gives me a blank screen.

but when I use a simple script like this :

<?php
$handle=opendir('.');
while (false!=($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file";
}
}
closedir($handle);
?>

it would work and display the files.
But I want it to display in descending order and only limit to 20 files.

thanx
