php - 如何用 php 读取 json 解码数组？

Question

我有以下数组，但我不知道如何从中获取任何值，这是数组:

Array
(
    [0] => stdClass Object
        (
            [aure] => test
            [menu] => stdClass Object
                (
                    [pizza] => stdClass Object
                        (
                            [Tomato & Cheese] => stdClass Object
                                (
                                    [small] => 5.50
                                    [large] => 9.75
                                )

                            [onion] => stdClass Object
                                (
                                    [small] => 5.50
                                    [large] => 9.75
                                )

                        )

                    [Special Dinners] => stdClass Object
                        (
                            [Chicken Wings Dinner] => stdClass Object
                                (
                                    [price] => 15.80
                                )

                            [onion] => stdClass Object
                                (
                                    [small] => 5.50
                                    [large] => 9.75
                                )

                        )

                )

        )

)

您能举个例子说明我怎样才能知道小番茄奶酪披萨的价格吗？

Answer 1

$array[0]->menu->pizza->{"Tomato & Cheese"}->small;

我使用了花括号，因为没有它们我无法获得“番茄和奶酪”(它们有空格)

这会给你所有的披萨

$pizzas = (array) $array[0]->menu->pizza;
foreach($pizzas as $pizzaname => $choices){
    echo $pizzaname." (small) is for ".$choices->small."<br />";
    echo $pizzaname." (large) is for ".$choices->large."<br />";
}
