There's a couple of issues with PHP configuration related to file
uploads you should be aware of :

1. Limitations on script execution time

First limitation is on "input" time (max_input_time) - that is, how
much time is spent receiving information. Default value is 60s.

Second one is on script execution time (max_execution_time) and is
30s.

These values can be changed with set_time_limit() (http://www.php.net/
function.set-time-limit) but only if PHP is not running in "safe
mode".

2. Limitations on upload size

There are 2 options, which seem to be both relevant: post_max_size and
upload_max_filesize - values tend to differ greately from host to
host.

You can figure out settings for your partiular host with phpinfo().

One option to overcome these limitations is to use a perl script on
the receiving end. On some hosts this allows for check the upload
progress too - tho not on mine :)

Hope my comments have been of help,
