mysql error statements not working

[ayoubel12]

Hello, please can someone help me? I want when the admin tries to connect using wrong database information to be redirected to an other error page but it don't work  even if I try to echo a message. Here is my code containing wrong database name :

<?php
  $host = "localhost";
  $user = "root";
  $pass = "";
  $dbname = "ts";

$dbcon = mysqli_connect($host,$user,$pass,$dbname);

if($dbcon){
  echo 'connection success';
}else{
  header("Location: dberror.php");
  die();
}
?>

Here is what displays to me instead of redirecting the user to the error page:

Fatal error: Uncaught mysqli_sql_exception: Unknown database 'ts' in C:\xampp\htdocs\tst\dbcon.php:7 Stack trace: #0 C:\xampp\htdocs\tst\dbcon.php(7): mysqli_connect('localhost', 'root', '', 'ts') #1 {main} thrown in C:\xampp\htdocs\tst\dbcon.php on line 7

 

I would want to know what's wrong? 

Thanks in advance.
