What are the best practices for handling case sensitivity issues when working with JSON data in PHP?

Case sensitivity can be an issue when working with JSON data in PHP because JSON keys are case-sensitive. To handle this issue, you can convert all keys to a consistent case, such as lowercase, before accessing the data. This ensures that your code will work correctly regardless of the case used in the JSON data. 

// Sample JSON data
$jsonData = '{"Name": "John", "Age": 30}';

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

// Convert keys to lowercase
$data = array_change_key_case($data, CASE_LOWER);

// Access data using lowercase keys
$name = $data['name'];
$age = $data['age'];

echo $name; // Output: John
echo $age; // Output: 30
