How can JSON data be effectively managed and updated in PHP applications, as shown in the code snippet?

To effectively manage and update JSON data in PHP applications, you can read the JSON data from a file, decode it into an associative array, make changes to the array as needed, encode the array back to JSON format, and then write it back to the file. This process ensures that the JSON data is properly managed and updated within the PHP application. 

// Read JSON data from a file
$jsonData = file_get_contents('data.json');

// Decode JSON data into an associative array
$data = json_decode($jsonData, true);

// Make changes to the array as needed
$data['key'] = 'value';

// Encode the array back to JSON format
$newJsonData = json_encode($data);

// Write the updated JSON data back to the file
file_put_contents('data.json', $newJsonData);
