How can one ensure that the MySQL database connection is properly established in PHP when using PHP-kit?

To ensure that the MySQL database connection is properly established in PHP when using PHP-kit, you need to make sure that the connection parameters are correct and that the connection is successfully established. You can use the mysqli_connect() function to establish a connection to the MySQL database and handle any errors that may occur during the connection process.

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

// Create connection
$conn = mysqli_connect($servername, $username, $password, $database);

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