PHP custom errors

: This article mainly introduces PHP user-defined errors. if you are interested in PHP tutorials, refer to them. Custom errors allow you to completely control the errors and their prompts.

Set errors are handled by defined functions.

Set_error_handler ('errname ');

Set this function and customize the input and record of errors. four parameters are provided.
ErrNo error code
ErrMsg error message
ErrFile error file
ErrLine error row number

FunctionerrName ($ errNo, $ errMsg, $ errFile, $ errLine) {echo 'errno: '. $ errno '.
'; Echo 'errmsg:'. $ errMsg '.
'; Echo 'errfile:'. $ errFile '.
'; Echo 'errline:'. $ errLine .'
';} Trigger_error ('error! ', E_USER_NOTICE );

Note:

• If a custom error is used, the system will not handle the error;
• In the event of a serious error (E_ERROR, E_USER_ERROR), the program will be immediately stopped, that is, the custom error function cannot be processed, and the system will handle the error.

'). AddClass ('pre-numbering '). hide (); $ (this ). addClass ('Has-numbering '). parent (). append ($ numbering); for (I = 1; I <= lines; I ++) {$ numbering. append ($ ('

'). Text (I) ;}; $ numbering. fadeIn (1700) ;}) ;}; script

The above describes PHP user-defined errors, including some content, and hope to help those who are interested in PHP tutorials.
