To customise own php ini settings use own custom *.ini file PHP-FPM - CentminMod.com LEMP Nginx web stack for CentOS and reference Zend Opcache ini options PHP: Runtime Configuration - Manual

Relevant settings for when new PHP file changes are detected by PHP

Note lowering opcache.revalidate_freq from 180 seconds default or disabling with 0 will reduce PHP performance. You can keep 180s default and just restart php-fpm service after php file changes to flush cache instead which is what you should do after changing php files and need cache to update before 180 second timeout
