What are the best practices for handling errors and exceptions when working with JSON data in PHP?

When working with JSON data in PHP, it is important to handle errors and exceptions properly to ensure the stability and security of your application. One common practice is to use try-catch blocks to catch any exceptions that may occur during JSON decoding or encoding operations. Additionally, you can use functions like json_last_error() to check for errors and handle them accordingly. 

try {
    $jsonData = json_decode($jsonString);
    
    if (json_last_error() !== JSON_ERROR_NONE) {
        throw new Exception('Error decoding JSON: ' . json_last_error_msg());
    }

    // Process the decoded JSON data

} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
