max_file_uploads INI_PERDIR

I'd like to add PHP_INI_PERDIR to max_file_uploads before 5.4.0 and also in the next 5.3 release. This setting is very similar in scope to max_input_vars and other POST-related limiters like upload_max_filesize, and post_max_size all of which are PHP_INI_SYSTEM|PHP_INI_PERDIR. The main reason is that our default for max_file_uploads is rather low and since we count empty uploads against this limit it is easy for apps to hit this. So if you have more than 20 type="file" fields in a form, even if the user only actually uploads a single file, it will hit this limit and fail. The change it trivial and since it eases a restriction and doesn't tighten one, it isn't going to break anything: http://svn.php.net/viewvc/php/php-src/trunk/main/main.c?r1=323245&r2=323296 Any objections from anyone? Stas on the 5.4.0 merge? Johannes on the 5.3.11? One example of pain this is currently causing: http://allinthehead.com/retro/349/the-curse-of-max_file_uploads -Rasmus
