PHP error handler - how to get error name

Question

i have my own error_handler:

$error = new Error();
set_error_handler(array($error,"catchError"));


class Error{    
    public function catchError($err_no, $err_str, $err_file, $err_line, $err_context){
            print_r($err_no); 
    }
}

If i cause error of type "E_WARNING" this error catcher writes just "2". How i force him to write "E_WRNING"?

I wonder, if is possible get error name from this "2" code. Thank you very much!

Answer 1

switch ($err_no) {
    case E_WARNING :
        echo 'E_WARNING';
        break;
    case E_NOTICE :
        echo 'E_NOTICE';
        break;
    ...
}

Alternatively an array:

$errors = array(
    E_WARNING => 'E_WARNING',
    E_NOTICE  => 'E_NOTICE',
    ...
);

echo $errors[$err_no];

For all types you want to handle from this list: http://php.net/manual/en/errorfunc.constants.php
Typically you'd handle different error levels differently, not just echo the name of the constant.
