如何调整PHP错误报告级别

php.ini文件

 

; error_reporting is a bit-field.  Or each number up to get desired error

; reporting level

; 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 message

;

; Examples:

;

;   - Show all errors, except for notices and coding standards warnings

;

;error_reporting = E_ALL & ~E_NOTICE

;

;   - Show all errors, except for notices

;

;error_reporting = E_ALL & ~E_NOTICE | E_STRICT

;

;   - Show only errors

;

;error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR

;

;   - Show all errors, except coding standards warnings

;

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT

 

; Print out errors (as a part of the output).  For production web sites,

; you're strongly encouraged to turn this feature off, and use error logging

; instead (see below).  Keeping display_errors enabled on a production web site

; may reveal security information to end users, such as file paths on your Web

; server, your database schema or other information.

;

; possible values for display_errors:

;

; Off          - Do not display any errors 

; stderr       - Display errors to STDERR (affects only CGI/CLI binaries!)   

; On or stdout - Display errors to STDOUT (default)

;  

; To output errors to STDERR with CGI/CLI:              

;display_errors = "stderr"

;

; Default

;

display_errors = On
