I've got a form to upload a file, but if I try to upload anything larger than 2MB it fails with $_FILES['userfile']['error'] being set to 1, which means the file was larger than the limit set in upload_max_filesize. My upload_max_filesize is set to 10M, though, as well as post_max_size and the form's max_file_size. The source is below and you can try it for yourself here. The values in the grey box @ the bottom are being pulled from ini_get(), so that shows that the values are set correctly. I've done a lot of searching but can't find any reason why it would say that the limit is 10MB, but that a 2MB file is over the limit. It's running under IIS, so it isn't the RequestBodyLimit issue.

It looks like even though phpinfo() and ini_get are telling me that the directives are set to higher than the default, they're really not. I upped the default upload_max_filesize to 8M and now I can upload up to that, but if I go over it errors out. I've got the max_input_time set @ 240 seconds, but it still stops @ 60 (the default).

 

This is a Windows server running IIS6 and PHP 5.2. I'm using the registry to override the default values. Putting a custom php.ini in the directory didn't work, and that's a sloppy method anyway. Any ideas on why PHP is saying that the values are being overridden, but they really aren't?
