Display_errors = ON/* PHP configuration file path:/uer/local/php/etc/php.ini * *

Copy Code code as follows:

error_reporting = E_all; /* The most stringent error reporting level, the development phase can be opened * *
error_reporting = E_all &~ e_notice/* ERROR other than NOTICE * *
error_reporting = E_error | E_parse | E_core_error/* Only considers fatal Run-time errors, new parse errors and core errors * *
