When should JSON be used instead of serialization in PHP for storing data?

JSON should be used instead of serialization in PHP for storing data when you need a more human-readable and interoperable format. JSON is widely supported across different programming languages and platforms, making it easier to share data between systems. Additionally, JSON is more lightweight compared to serialized data, which can lead to better performance. 

// Serialize data
$data = ['name' => 'John', 'age' => 30];
$serializedData = serialize($data);

// Store serialized data in a file
file_put_contents('data.txt', $serializedData);

// JSON encode data
$jsonData = json_encode($data);

// Store JSON data in a file
file_put_contents('data.json', $jsonData);
