What best practices should be followed when handling JSON data in PHP scripts for database operations?

When handling JSON data in PHP scripts for database operations, it is important to properly sanitize and validate the input to prevent SQL injection attacks. Additionally, it is recommended to use prepared statements to securely execute database queries. Finally, always handle errors and exceptions gracefully to provide informative feedback to the user. 

// Sample code snippet for handling JSON data in PHP scripts for database operations

// Assuming $jsonData contains the JSON data
$jsonData = '{"name": "John", "age": 30}';

// Decode the JSON data
$data = json_decode($jsonData, true);

// Sanitize and validate the input data
$name = filter_var($data['name'], FILTER_SANITIZE_STRING);
$age = filter_var($data['age'], FILTER_VALIDATE_INT);

// Prepare and execute a database query using PDO prepared statements
$stmt = $pdo->prepare("INSERT INTO users (name, age) VALUES (:name, :age)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':age', $age);
$stmt->execute();

// Handle errors and exceptions
if($stmt->errorCode() !== '00000'){
    echo "Error: " . implode(", ", $stmt->errorInfo());
}
