如何用php读取json解码数组？

我有以下数组,我无法弄清楚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
                                )

                        )

                )

        )

)

你能不能给我一个例子,说明我怎样才能得到一个小番茄的价格？芝士披萨？

解决方法:

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

我使用了大括号,因为没有它们我就无法得到“番茄和奶酪”(它们有空格)

这将给你所有的比萨饼

$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 />";
}
