How can setting the second parameter of json_decode to true help in accessing elements of a JSON object in PHP?

Setting the second parameter of json_decode to true will return the JSON object as an associative array in PHP, making it easier to access elements using keys rather than object notation. This can be useful when dealing with nested JSON objects or when needing to access specific values within the JSON data. 

$json_string = '{"name": "John", "age": 30}';
$decoded_data = json_decode($json_string, true);

echo $decoded_data['name']; // Output: John
echo $decoded_data['age']; // Output: 30
