How can the use of the mysql_ functions in PHP be improved to adhere to best practices and modern standards?

The use of mysql_ functions in PHP should be improved by transitioning to mysqli or PDO for database interactions. This is because the mysql_ functions are deprecated and no longer recommended for use due to security vulnerabilities and lack of support for newer MySQL features. By using mysqli or PDO, developers can ensure better security, prepared statements for preventing SQL injection attacks, and compatibility with the latest MySQL versions. 

// Connect to the database using mysqli
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

if ($mysqli->connect_error) {
    die('Connection failed: ' . $mysqli->connect_error);
}

// Perform a query using prepared statements
$stmt = $mysqli->prepare("SELECT * FROM table WHERE id = ?");
$stmt->bind_param('i', $id);
$id = 1;
$stmt->execute();
$result = $stmt->get_result();

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

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