PHP - Hash contents of uploaded file

I would like to hash the contents of an uploaded file in MD5. The file will not be saved locally so it only exists in a tmp directory.

How can I do this? Thanks.

You can use md5_file() or sha1_file() function. For example, if your post variable is filevar:

$myhash = md5_file($_FILES['filevar']['tmp_name']);

You can use md5_file(), even on your temporary file.
