The upload_max_filesize and post_max_size ini settings cannot be set
from within a script, because by the time your script has started any
larger uploads would have already been discarded.

You'll need to set them in .htaccess or virtual host in order for them
to have any effect.

In .htaccess, you would want something like:

# tell php to allow large uploads
php_value upload_max_filesize "16M"
php_value post_max_size "50M"
php_value max_execution_time 60
php_value max_input_time 600

# tell apache to allow large uploads
LimitRequestBody 53000000

If you want to restrict the settings to a particular script, you could
use a <Location> block.
