使用php解析2头json和分组

我有一个类似这样的json，但不知道如何使用php在名称标题下解析并显示在选择框中 命名客户，Lead.So每个值都将显示在这些标题下。 第一步是

$data = json_decode($json);

一个foreach会提供结果吗？但是如何显示头部名称呢

{
    "status": {
        "message": "success",
        "code": 200
    },
    "clients": [
        {
            "values": [
                {
                    "Code": "rdf",
                    "name": "Adfgf"
                },
                {
                    "Code": "fg",
                    "name": "fg"
                }
            ],
            "name": "Customers"
        },
        {
            "values": [
                {
                    "Code": "fgf",
                    "name": "fgdf"
                },
                {
                    "Code": "api",
                    "name": "fgfdgd"
                },
                {
                    "Code": "fgbb",
                    "name": "mnn"
                },
                {
                    "Code": "acy",
                    "name": "System"
                }
            ],
            "name": "Lead"
        }
    ]
}

这不是有效的JSON：它是从webservice获取的，当我在chrome插件中检查REST客户端时，它的返回是这样的。你需要回显原始JSON并发布它。@AbraCadaver我已经更新了有效代码第一步是$data=JSON\u decode$JSON；那是一辆福特车吗？

$string = '{
    "status": {
        "message": "success",
        "code": 200
    },
    "clients": [
        {
            "values": [
                {
                    "Code": "rdf",
                    "name": "first"
                },
                {
                    "Code": "fg",
                    "name": "second"
                }
            ],
            "name": "Customers"
        },
        {
            "values": [
                {
                    "Code": "fgf",
                    "name": "third"
                },
                {
                    "Code": "api",
                    "name": "4th"
                },
                {
                    "Code": "fgbb",
                    "name": "5th"
                },
                {
                    "Code": "acy",
                    "name": "last"
                }
            ],
            "name": "Lead"
        }
    ]
}';

$data = json_decode($string,true);

echo "<Select>";
foreach ($data['clients'] as $c) {

    $gp =$c['name'];
   echo "<optgroup label=$gp>";

    # calling the function on the values data       
    recurse($c['values']);
   echo  '</optgroup>';

}

function recurse($arr, $level = 0){
    # we have a numerically-indexed array. go through each item:
    foreach ($arr as $n) {
        # print out the item ID and the item name
        echo '<option value="' . $n['Code'] . '">' 
        . $n['name']
        . '</option>'
        ;

    }

}
 echo "</Select>";
