What are some best practices for error handling when working with JSON data in PHP?

When working with JSON data in PHP, it is important to implement proper error handling to ensure that your code can gracefully handle any issues that may arise, such as invalid JSON syntax or missing data. One common best practice is to use try-catch blocks when decoding JSON data to catch any potential errors and handle them appropriately. 

try {
    $jsonString = '{"key": "value"}';
    $jsonData = json_decode($jsonString);
    
    if (json_last_error() !== JSON_ERROR_NONE) {
        throw new Exception('Error decoding JSON: ' . json_last_error_msg());
    }
    
    // Use $jsonData here
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
