来自脚本的error_reporting - > nginx + php-fpm

i am using nginx+php-fpm. I am unable to set up error displaying via php-file like this: error_reporting(0); or ini_set('error_reporting', E_ALL);

Working solution is via nginx.conf: fastcgi_param PHP_VALUE "upload_max_filesize = 1000M post_max_size=1010M display_errors = On";

But I need via php-script :-). Is it possible? Thanks.

try

error_reporting(E_ALL);
ini_set('display_errors','on');

PS: 0 isn't a valid value for error reporting, there's predefined constants for that
