How can PHP developers effectively handle errors and exceptions when using Prepared Statements for database queries?

When using Prepared Statements for database queries in PHP, developers can effectively handle errors and exceptions by wrapping the query execution in a try-catch block. This allows developers to catch any exceptions thrown during the query execution and handle them gracefully, such as logging the error or displaying a user-friendly message. 

try {
    $stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
    $stmt->bindParam(':id', $id);
    $stmt->execute();
    
    // Fetch results
    $result = $stmt->fetch();
    
    // Handle the fetched data
    
} catch (PDOException $e) {
    // Handle the exception, such as logging the error or displaying a user-friendly message
    echo "An error occurred: " . $e->getMessage();
}
