在PHP上更改upload_max_filesize

Question

I'm using PHP 5.3.0 and have encountered something that might be a bug (in which case I'll report it) or might be me - so I'm asking to make sure.

When running this code:

<?php
ini_set('upload_max_filesize', '10M');
echo ini_get('upload_max_filesize'), ", " , ini_get('post_max_size')

I end up with:

2M, 8M

This is despite my php.ini setting these higher:

upload_max_filesize = 10M
post_max_size = 10M

(occuring only once)

Because the error occurs after setting the value as well as it being set in php.ini I'm inclined to think it's a bug. Can anyone confirm or point me where I'm going wrong?

Update: Looks like restarting Apache fixed this - I always thought it didn't need to be restarted if you changed php.ini.

Answer 1

You can't use shorthand notation to set configuration values outside of PHP.ini. I assume it's falling back to 2MB as the compiled default when confronted with a bad value.

On the other hand, I don't think upload_max_filesize could be set using ini_set(). The "official" list states that it is PHP_INI_PERDIR .
