What steps can be taken to ensure compatibility between PHP and the web hosting server for database operations?

To ensure compatibility between PHP and the web hosting server for database operations, it is important to check the PHP version and the database server version to ensure they are compatible. Additionally, make sure that the necessary PHP extensions for database connectivity (like mysqli or PDO) are installed and enabled on the server. Finally, verify that the database credentials in the PHP code match the database credentials set up on the server. 

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