Question

我有以下阵列,我可以说明如何从中获取任何价值,即:

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
                                )

                        )

                )

        )

)

你们能给我一个例子,说明我如何能够为小托马和安乐团获得价格?

Answer 1

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

我使用了曲解的括号,因为Im无法在没有“Tomato & Cheese”的情况下获得“Tomato &”;

这将使你们都能得到所有药品。

$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 />";
}

Answer 2

如果你的名字不单是字母数字,则考虑确定<代码>assoc para amount of json_decode,以真实方式获取一个nes词而不是物体。

然而,你仍然可以使用下列辛迪加获得奇怪的成员名称:

echo  Large t&c:   . jsonArray[0]->menu->pizza->{ Tomato & Cheese }->large;
