I have done large file uploads in PHP.  Make sure you have the following
set in php.ini:

upload_max_filesize = <some large size followed by M for megabyte or G
for gigabyte>
file_uploads = on
post_max_size = <some large size>

Also, you can set these values through the set_ini function in PHP so
that it can be per script instead of effective for every script which
can allow for a more granular level of control for security reasons, etc.

I have never used the form input value, nor should you have to change
the memory_limit very much since the file itself is not loaded into
memory, just information regarding the file.
