如何在PHP中循环遍历此json解码数据? [英] How to loop through this json decoded data in PHP?

问题描述

我有需要解码的JSON产品列表:

I've have this list of products in JSON that needs to be decoded:

"[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]"

使用json_decode()在PHP中对其进行解码后，我不知道输出是哪种结构.我以为它将是一个数组，但是在我要求count()之后，它说它是"0".如何遍历这些数据，以便获得列表中每种产品的属性.

After I decode it in PHP with json_decode(), I have no idea what kind of structure the output is. I assumed that it would be an array, but after I ask for count() it says its "0". How can I loop through this data so that I get the attributes of each product on the list.

谢谢！
