var/tmp/phpAAAOeayLL is a tmp file name that forces the file name to be unique.
in your upload form check to see what you've got for the filename. example:
<INPUT NAME="userfile" TYPE="file">
after the file has been uploaded $userfile would contain the temp file name and $userfile_name would contain the name of the file on the senders system.
