PHP打印stdClass对象

Question

我有以下stdClass，如何在里面打印对象数据？

Array
(
    [USD] => stdClass Object
        (
            [15m] => 94.60177
            [last] => 94.60177
            [buy] => 94.61019
            [sell] => 94.66024
            [24h] => 94.51
            [symbol] => $
        )

    [CNY] => stdClass Object
        (
            [15m] => 580.38036
            [last] => 580.38036
            [buy] => 569.24441
            [sell] => 593.90802
            [24h] => 577.26
            [symbol] => ¥
        )
)

我需要访问例如USD-> 15m 试过像$blockchain_array->USD->15m这样没有运气的东西。 谢谢！

Answer 1

你走了。

echo $blockchain_array['USD']->{'15m'};

Answer 2

$blockchain_array['USD']->{'15m'}
