How can PHP beginners ensure they have set up the necessary permissions and configurations for PHP to interact with a database successfully?

PHP beginners can ensure they have set up the necessary permissions and configurations for PHP to interact with a database successfully by making sure that the database credentials (such as username, password, database name) are correct in their PHP code, and that the database user has the proper permissions to access the database. Additionally, they should check that the PHP extension for the database they are using is installed and enabled in their PHP configuration. 

<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "my_database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
