Hi all,

I am not a developer, but I work with several and am posting this for
them. We are trying to determine whether it is possible to check the
size of a file before a user uploads it.

Everything I've read suggests that this is impossible (or at least very
difficult) in PHP, and this makes sense for a server-side language.
What gives me pause, however, is the fact that when a user tries to
upload a file larger than the max file size we allow, an error appears
in our error log immediately -- yet the upload continues.

So somehow PHP must be recognizing that the file is too big well before
it's been uploaded. The question is how -- and how do we make the leap
from that recognition to an immediate halt of the upload?
