Description:
------------
PHP loads entire uploaded files into RAM, which makes the feature useless except for toy websites.  PHP should be smart enough to spool large uploads to disk, like CGI.pm does.

It would also be very nice if there were a way to get the name of the temp file spooled to, so that the user can be given feedback on their upload as it progresses, but this is not necessary.

I'm putting this in as a feature request, because I know you guys don't consider it a bug.

From http://www.php.net/manual/en/features.file-upload.php :

"Files will by default be stored in the server's default temporary directory, unless another location has been given with the upload_tmp_dir directive in php.ini."

"$_FILES['userfile']['tmp_name'] The temporary filename of the file in which the uploaded file was stored on the server."

Correct me if I am wrong, but since PHP caches the whole file in RAM before writing it out, that temp file name would be useless for purposes for letting the user know the progress of their upload (such as percentage complete).

There's an inofficial patch for progress-bars, you can find it at http://pdoru.from.ro/

PHP does NOT store the entire file in memory. (since version 4.2.0)
