How should variable naming conventions be adhered to in PHP to prevent potential errors in database operations?

Variable naming conventions should be adhered to in PHP to prevent potential errors in database operations by ensuring that variables are named in a clear and consistent manner. This helps to avoid confusion and mistakes when working with database queries and results. 

// Example of adhering to variable naming conventions in PHP for database operations

// Define variables with clear and meaningful names
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";

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

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