What are some best practices for handling and manipulating JSON data in PHP applications?

When working with JSON data in PHP applications, it is important to use built-in functions for encoding and decoding JSON data to ensure data integrity and security. Additionally, it is recommended to validate JSON data before processing it to prevent potential errors or vulnerabilities in your application. 

// Example of decoding JSON data in PHP
$jsonData = '{"name": "John", "age": 30, "city": "New York"}';
$data = json_decode($jsonData);

if($data === null) {
    // Handle invalid JSON data
    die('Invalid JSON data');
}

// Accessing decoded JSON data
echo $data->name; // Output: John
echo $data->age; // Output: 30
echo $data->city; // Output: New York
