请问怎么关错误提示呀？像notice什么的，就直接屏蔽掉？ [ 新手入门 ]

php.ini中配置：error_reporting = E_ALL & ~E_NOTICE 除了NOTICE，其他都显示。
还有很多错误级别：

; E_ALL             - All errors and warnings (doesn't include E_STRICT)
; E_ERROR           - fatal run-time errors
; E_RECOVERABLE_ERROR  - almost fatal run-time errors
; E_WARNING         - run-time warnings (non-fatal errors)
; E_PARSE           - compile-time parse errors
; E_NOTICE          - run-time notices (these are warnings which often result
;                     from a bug in your code, but it's possible that it was
;                     intentional (e.g., using an uninitialized variable and
;                     relying on the fact it's automatically initialized to an
;                     empty string)
; E_STRICT          - run-time notices, enable to have PHP suggest changes
;                     to your code which will ensure the best interoperability
;                     and forward compatibility of your code
; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's
;                     initial startup
; E_COMPILE_ERROR   - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR      - user-generated error message
; E_USER_WARNING    - user-generated warning message
; E_USER_NOTICE     - user-generated notice messag

现在的情况是，memcache连不上时，直接500错误，程序停掉了。不想要memcache 影响到正常的数据库处理。

谢谢版主大人，按你说的方法好了

在入口文件里屏蔽：

error_reporting (0);
defined('YII_DEBUG') or define('YII_DEBUG',true);

配置中增加：
'errorHandler' => [

'errorAction' => '/site/error'

],
但是notice错并不执行该回调，楼主知道怎么解决吗？
