Warning: If you save a md5_file hash in a database to keep record of uploaded files, which is
usefull to prevent users from uploading the same file twice, be aware that after using
move_uploaded_file the md5_file hash changes! And you are unable to find the corresponding hash and
delete it in the database, when a file is deleted.
