javascript - 如何解析这种json数组

Question

我有一个类似 blew 的 json 数组:

    {
    "0": {
        "kind": "mammal",
        "name": "Pussy the Cat",
        "weight": "12kg",
        "age": "5"
    },
    "1": {
        "kind": "mammal",
        "name": "Roxy the Dog",
        "weight": "25kg",
        "age": "8"
    },
    "2": {
        "kind": "fish",
        "name": "Piranha the Fish",
        "weight": "1kg",
        "age": "1"
    },
    "3": {
        "kind": "bird",
        "name": "Einstein the Parrot",
        "weight": "0.5kg",
        "age": "4"
    }
}

我删除了一个元素“Piranha the Fish”(未设置)我的 json 代码更改为 blow:

{
    "0": {
        "kind": "mammal",
        "name": "Pussy the Cat",
        "weight": "12kg",
        "age": "5"
    },
    "1": {
        "kind": "mammal",
        "name": "Roxy the Dog",
        "weight": "25kg",
        "age": "8"
    },
    "3": {
        "kind": "bird",
        "name": "Einstein the Parrot",
        "weight": "0.5kg",
        "age": "4"
    }
}

当我删除元素时，元素的计数器变为 0,1,3 所以现在我无法完全访问我的 json 元素

我想要这段代码的回显值:

for ($i = 0; $i < $JsonCount - 1; $i++) {
    echo "Name :";
    echo $json_cod[$i]['name'];
    echo "<br/>";
    echo "Age :";
    echo $json_cod[$i]['age'];
    echo "<br/>";
}

输出:

Name :Pussy the Cat
Age :5
Name :Roxy the Dog
Age :8

Answer 1

尝试使用 foreach。

foreach ($json_cod as $item) {
  echo "Name :";echo $item['name'];echo "<br/>";
  echo "Age :";echo $item['age'];echo "<br/>";
}
