Im testing my database and validation scripts in php. After changing the database password to run the error script, it is not displaying the message, but instead displaying a white blank page.

Im simply looking to display whatever the error message is. Here is my code:

Database.php

<?php

$host = "localhost";
$dbname = "login_db";
$username = "root";
$password = "xxx";

# connect to sql database
$mysqli = new mysqli($host, $username, $password, $dbname);

if ($mysqli->connect_errno) {
    die("Connection error: " . $mysqli->connect_error);
}

return $mysqli;

Auth.php

$mysqli = require __DIR__ . "/database.php";

print_r($_POST);

I’ve tried changing the path of the php folder, but the results have been the same. Also, I’ve attached a screenshot of my text editor file path for more context.
