What are the necessary steps to take a PHP website with a database from a local server to an online server?

To move a PHP website with a database from a local server to an online server, you will need to export your local database, create a new database on the online server, import the exported database, update your website's database connection settings to point to the online server, and upload your website files to the online server. 

// Example code to update database connection settings in PHP
$servername = "online_server";
$username = "online_username";
$password = "online_password";
$dbname = "online_database";

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

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