How can PHP developers ensure stability and security when using mysqli functions in their code?

To ensure stability and security when using mysqli functions in PHP code, developers should always use prepared statements to prevent SQL injection attacks and parameterize their queries. Additionally, developers should properly handle errors and exceptions to maintain stability in their code. 

// Example of using prepared statements with mysqli to ensure security and stability
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare a statement
$stmt = $mysqli->prepare("SELECT * FROM users WHERE username = ?");

// Bind parameters
$stmt->bind_param("s", $username);

// Set parameters and execute
$username = "example_user";
$stmt->execute();

// Get result
$result = $stmt->get_result();

// Fetch data
while ($row = $result->fetch_assoc()) {
    // Process data
}

// Close statement and connection
$stmt->close();
$mysqli->close();
