通过电子邮件php发送错误消息

Question

I want to get a mail if any error occurs in my php apps. I found an example on https://www.w3schools.com/php/php_error.asp :

<?php
    //error handler function
function customError($errno, $errstr) {
  echo "<b>Error:</b> [$errno] $errstr<br>";
  echo "Webmaster has been notified";
  error_log("Error: [$errno] $errstr",1,
  "uwe.nachname@gmail.com","From: webmaster@example.com");
}
//set error handler
set_error_handler("customError",E_USER_WARNING);
//trigger error
$test=2;
if ($test>=1) {
  trigger_error("Value must be 1 or below",E_USER_WARNING);
}
?>

This is working, but when I change it for all errors not:

<?php
    error_reporting(E_ALL);
ini_set('display_errors', 'Off');
//error handler function
function customError($errno, $errstr) {
  echo "<b>Error:</b> [$errno] $errstr<br>";
  echo "Webmaster has been notified";
  error_log("Error: [$errno] $errstr",1,
  "uwe.nachname@gmail.com","From: webmaster@example.com");
}
//set error handler
set_error_handler("customError",E_ALL);
  echo 'now the error: ';
  echo gibtsnicht();
?>

What can I do to get a mail for any error?? Thanks and greetings from Austria Uwe

The issue is that this is not triggering an error, but an exception, so the exception has to be caught and handled.

<?php
function customException($ex) {
  echo "<b>Exception:</b> ".$ex->getMessage()." Line: ".$ex->getLine() ."<br>";
  error_log("Exception: " .$ex->getMessage()." File: ".$ex->getFile()." Line: ".$ex->getLine(),1,
  "uwe.nachname@gmail.com","From: webmaster@example.com");
  echo "Webmaster has been notified";
}

set_exception_handler("customException"); 
  echo 'now the exception: <br>';
  echo gibtsnicht();
?>

Check out Exception
