Uploading And Creating Random Names

[SP8600]

Hi, if i use the code below is there any way in which i could change the file name as it is being uploaded, to a random number.

$path = "C:/wwwroot/pp/images/pp";
$url_images = "http://javelin.dns2go.com/pp/images";
$max_size = 1000000;

//Upload Thumbnail
if (is_uploaded_file($thumbnail)) {

if ($thumbnail_size>$max_size) { echo "The file is too big<br>\n"; exit; }

if (($thumbnail_type=="image/gif") || ($thumbnail_type=="image/pjpeg")) {

if (file_exists($path . $thumbnail_name)) { echo "The file already exists<br>\n"; exit; }

$res = copy($thumbnail, $path . $thumbnail_name);
if (!$res) {
echo "upload failed!<br>\n"; exit; }
else
echo "upload sucessful<br>\n";

echo "File Name: $thumbnail_name<br>\n";
echo "File Size: $thumbnail_size bytes<br>\n";
echo "File Type: $thumbnail_type<br>\n";
} else { echo "Wrong file type<br>\n"; exit; }

}

Are you sure you want to use random numbers?
Isn't there a prob. that you will duplicate names?

why not base the name on the time down to sec?

use the date function to generate a number based on month_day_sec and end it with ".x" this way, you can explode the file name (if you'd like) to sort the results of the directory and do all sorts of other things. (i.e. auto delete after some amount of time).
