How can PHP developers ensure that the encoding settings in their database connections are correct?

PHP developers can ensure that the encoding settings in their database connections are correct by explicitly setting the character set when establishing the connection. This can be done by adding 'charset=utf8mb4' to the connection string or by executing a query to set the character set after the connection is established. 

// Establishing a connection with correct encoding settings
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Set the character set
$conn->set_charset("utf8mb4");
