using asort()

[Anon]

I am trying to sort the files in a directory. I am not sure if it is possible to asort() on this type of php:

$handle=opendir("/home/groupvertical/www/pellegirl/pdf/owspring/");
while ($file = (readdir($handle))

thanks for the help

well, assumedly you could set each file as an array value and then use asort() or natsort() on them... what are you trying to use it for? heres what natsort does:
http://www.php.net/manual/en/function.natsort.php
on that note, can anyone tell me if theres a way to get a case-insensitive asort?

I am reading files from a selected directory into links for downloads.Any suggestions on how to have these come out ascending order.

Here is the full code:

$handle=opendir("/home/groupvertical/www/pellegirl/pdf/owspring/");
while ($file = readdir($handle))
{
if ($file == "." || $file == "..")
{ }
else
{
echo "-"; // makes the bulleted list
print "<a href=\"/pellegirl/pdf/owspring/$file\" target=\"_blank\">$file</a><br>\n";
}
}
closedir($handle);
