PHP reading a directory files

[Anon]

I can open a directory and get it to display all the files.

However, how do I change this code so that it displays
a) Files from the latest date created in descending order(latest files on top)
and
b) Limit only the latest 20 files to be displayed.

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

thanx

In your loop, you can do something like this.

$filelist[$i]["name"] = $file;
$filelist[$i]["date"] = filemtime($file); // This function may need full path to file if opendir is called on something besides curdir.
++$i;

Then you can use usort on the array and then loop through the array until your counter > the size of the array or > 20.
