I've a setup with nginx + php-fpm. I found in my nginx error log a lot of PHP Warning messages like this:
2016/03/17 20:57:23 [error] 23002#0: *114868 FastCGI sent in stderr: "PHP message: PHP Warning: Declaration of Walker_Category_Filter::start_el(&$output, $category, $depth, $args) should be compatible with Walker_Category::start_el(&$output, $category, $depth = 0, $args = Array, $id = 0) in /var/www/wp-content/themes/venture/functions/theme/custom-post-types.php on line 0 PHP message: PHP Warning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /var/www/wp-includes/functions.php on line 3464", client: 188.8.131.52, server: www.myhost.net, request: "GET /appuntamenti/ HTTP/1.1", host: "www.myhost.net"
I don't want to log event like this, they fill up my logs and create a lot of rumors on New Relic reports. Do you knwow ho to change this behavior of nginx?
I've tried to change my php.ini configuration with this:
error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
The event are logged in nginx error log, so I think that's not related to php-fpm configuration.
Any suggestion is welcome
