PHP如何开启错误提示显示所有错误?

php 错误提示开启

开发环境项目,通常需要错误提示:php.ini文件,设置 display_errors = On

项目上线以后,当然不想把错误提示显示。

一般不直接修改php.ini文件,下面两行代码直接加入报错php文件:

ini_set("display_errors", "On");//打开错误提示
ini_set("error_reporting",E_ALL);//显示所有错误
Copy after login

error_reporting错误级别包括:

E_ALL             - 所有错误和警告(包括PHP 5.4.0中的E_STRICT)
E_ERROR           - 致命的运行时错误
E_RECOVERABLE_ERROR  - 几乎致命的运行时错误
E_WARNING         - 运行时警告(非致命错误)
E_PARSE           - 编译时解析错误
E_NOTICE          - 运行时通知(这些通常是警告,从您的代码中的错误,但它可能是故意的(例如,使用未初始化的变量和赖于它自动初始化为一个事实空字符串)
E_STRICT          - 运行时通知,允许PHP建议更改您的代码将确保最佳的互操作性,并转发代码的兼容性
E_CORE_ERROR      - PHP初始启动期间发生的致命错误
E_CORE_WARNING    - PHP期间发生的警告(非致命错误),初次启动
E_COMPILE_ERROR   - 致命的编译时错误
E_COMPILE_WARNING - 编译时警告(非致命错误)
E_USER_ERROR      - 用户生成的错误消息
E_USER_WARNING    - 用户生成的警告消息
E_USER_NOTICE     - 用户生成的通知消息
E_DEPRECATED      - 警告代码在将来的PHP版本中不起作用
E_USER_DEPRECATED - 用户生成的弃用警告
Copy after login

error_reporting最常见的几种设置:

E_ALL (显示所有错误,警告和通知,包括编码标准。)
E_ALL & ~E_NOTICE  (显示所有错误,通知除外)
E_ALL & ~E_NOTICE & ~E_STRICT  显示所有错误,通知和编码标准警告除外。)
E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (仅显示错误)
Copy after login
