upload file size

Hi
i really need help with an upload script.
right now i use
if ($HTTP_POST_FILES['userfile']['size']>$maxsize) { echo "File too big";
exit; }
to determine if the file is larger than allowed.
but the problem is, that if the file IS larger, it is still first fully
uploaded and then checked. i tested it several times - if the file is much
larger than allowed, it displays the error message but the page loads a lot
longer and my computer is sending the file to the server.
this could really kill my bandwidth. is there a way to check the file size
without fully uploading the file?

thanks
joe

correct. There are two solutions you can upload with a java applet, the
applet can be configured to lock the upload at a predefined limit. Would
save you a lot of bandwidth. The second is to upload via perl script,
which can check the Content-length header *before* processing the file
upload and block it. In fact megaupload - the php upload progress bar
that i did some time ago has this feature.

sorry about the belated reply message had been stuck in a que..

Joe
You would have to write a form validation script to check the file size.

You would have to write a javascript form validation script to check the
file size.
