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

// Access the data
$type = $data['type'];
$name = $data['name'];
$toppings = $data['toppings'];

// Access individual topping details
$firstTopping = $toppings[0];
$firstToppingId = $firstTopping['id'];
$firstToppingType = $firstTopping['type'];

// Print the data
echo "Type: $type\n";
echo "Name: $name\n";

echo "First Topping Type: $firstToppingType\n";

在此示例中，json_decode() 用于將 JSON 數(shù)據(jù)解碼為 PHP 關(guān)聯(lián)數(shù)組。然后，您可以像訪問任何 PHP 數(shù)組一樣訪問該數(shù)組的各個元素。
