What are best practices for parsing and decoding JSON data in PHP?

When parsing and decoding JSON data in PHP, it is best practice to use the json_decode() function to convert a JSON string into a PHP variable. This function will return an associative array or an object depending on the second parameter passed to it. It is also important to handle any errors that may occur during decoding to prevent unexpected behavior in your application.

// Sample JSON data
$jsonData = '{"name": "John", "age": 30, "city": "New York"}';

// Decode the JSON data
$decodedData = json_decode($jsonData);

// Check for errors during decoding
if ($decodedData === null && json_last_error() !== JSON_ERROR_NONE) {
    throw new Exception('Error decoding JSON: ' . json_last_error_msg());
}

// Access the decoded data
echo $decodedData->name; // Output: John
echo $decodedData->age; // Output: 30
echo $decodedData->city; // Output: New York
