Unix PHP Settings
From Novara Support Knowledgebase
In some cases you may need to override or increase one of the system wide limits defined by php.ini.
Under Unix web hosting you can locally override such a limit by creating a file called .htaccess and adding one or more lines similar to the ones below:
php_flag display_errors Off php_value upload_max_filesize 8M php_value safe_mode "1"
