  • E_PARSE – Compile-time parsing error

  • E_NOTICE – Run (These are often caused by bugs in your code, but can also be caused by intentional actions.)

  • E_STRICT – Coding standardization warnings, allowing PHP to suggest how to modify the code to ensure Optimal interoperability and forward compatibility.

  • E_CORE_ERROR - Fatal error during PHP startup initialization

  • E_CORE_WARNING - Warning (non-fatal error during PHP startup initialization) )

Example:

error_reporting = E_ALL & ~E_NOTICE ; 显示所有的错误,除了提醒
Copy after login
error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR ; 仅显示编译时致命性错误
