php ini - setting max_input_vars PHP.ini directive using ini_set

Question

Can I set the max_input_vars PHP.ini directive in my code? I have it set at the default 1000, however I have a script that has many checkboxes and text fields that could, and quite possibly will, go over the 1000 limit.

I'm using PHP 5.3.10 and i'm not getting any errors doing this. Also, I can't find any documentation that states I can't do this.

ini_set('max_input_vars', 3000);

Thanks.

max_input_vars has a changeable mode of PHP_INI_PERDIR meaning it can't be changed using ini_set (only in php.ini, .htaccess or httpd.conf)
