error_reportingThe parameters that can be set are as follows:

Error reporting is a bit field. You can add up the numbers to get the desired level of error reporting.

  • E_ALL – All errors and warnings (excluding E_STRICT)

  • E_ERROR – Fatal runtime errors

  • E_WARNING – Run-time warning (non-fatal error)

  • 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) )

  • E_COMPILE_ERROR - Compile-time fatal error

  • E_COMPILE_WARNING - Compile-time warning (non-fatal error)

  • E_USER_ERROR – User-defined error message

  • E_USER_WARNING – User-defined warning message

  • E_USER_NOTICE – User-defined The reminder message

is basically set to:

error_reporting = E_ALL & ~E_NOTICE ;

In addition to prompts, all errors are displayed.

Example:

error_reporting = E_ALL & ~E_NOTICE ; 显示所有的错误,除了提醒
error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR ; 仅显示编译时致命性错误
error_reporting=E_ERROR :只会报告致命性错误

In the php program, the setting for error_reporting is written as follows:

error_reporting(E_ALL);

//or other versions

  • 1 E_ERROR Fatal runtime error

  • 2 E_WARNING Runtime warning (non-fatal error)

  • 4 E_PARSE Compilation time parsing error

  • 8 E_NOTICE runtime reminder (often a bug, it may be intentional)

  • 16 E_CORE_ERROR PHP initialization at startup Fatal error in the process

  • 32 E_CORE_WARNING Warning (non-fatal error) in the initialization process when PHP starts up

  • 64 E_COMPILE_ERROR Fatal during compilation Sexual error

  • 128 E_COMPILE_WARNING Compile time warning (non-fatal error)

  • 256 E_USER_ERROR User-defined fatal error

  • 512 E_USER_WARNING User-defined warning (non-fatal error)

  • 1024 E_USER_NOTICE User-defined reminder (often a bug, it may be intentional)

  • 2048 E_STRICT Encoding standardization warning (recommended how to modify for forward compatibility)

  • 4096 E_RECOVERABLE_ERROR Near-fatal runtime error, if not Capture is treated as E_ERROR

  • ## 6143 E_ALL All errors except E_STRICT (8191 in PHP6, including all)
