Very nifty Brad,
One addition though, so she/you can work back from any point:
$i = 0;
$start = strtotime("2006-10-05 12:05am");
while(count($img_array) < 5) {
$year = date("Y", strtotime("-$i minutes", $start));
$month= date("m", strtotime("-$i minutes"

Yup. I break out of the loop if $i reaches 10 for some weird reason.
Also, depending on the frequency of files (i.e. are there months-worth
of gaps or minutes

$filename = "file.$hhmm.jpg";
if(file_exists("/path/to/$year/$month/$day/$hour/$filename")) {
$img_array[] = $filename;

Surely it would be simpler to store all this info in a database table? e.g.
id : int
created : timestamp
filename : varchar
Only files that actually existed would be in the DB, plus you could do all
your sorting on the 'created' timestamp column. Querying the DB should be
much simpler a
Hi Ashley,
Are all the files called file..jpg or could they have other names such
as clouds.1123.jpg, field.2034.jpg etc?
If they all have the same name, you could use something like scandir() and
then just use the first 5 items in the returned array.
You could also loop through the director
[] = $filename;
}
$i++;
}
print_r($img_array);

They are all the same exact file name with the only difference being
the timestamp.
Alternatively, you could get the OS to do the work through an exec call t
one solution could probably be made using: glob(), sort() and/or filemtime().
btw: I assume your aware that the filenames are not very unique (i.e. twice a
day, everyday a given file will potentially be overwritten) and that this
is intentional

sorry, clicked on send too fast ;)
i'd extract the minues and seconds , generate an array of timestamps and
sort that array "desc"
