问题描述

我收到此请求.

 { "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

，我想根据上述要求通过在数据库中搜索记录来提供对此的响应.我将如何解码上述json数组并分别使用每个区域字段.

and i want to provide response to this by searching records in database based on above request. how will i decode above json array and use each area field separately.

推荐答案

您的字符串不是有效的json开头.

your string is NOT a valid json to start with.

有效的json将是

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

如果您执行json_decode，它将产生

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

更新:以使用

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

输出:

kothrud
katraj

更新#2:

针对该true:

为TRUE时，返回的对象将转换为关联数组.有关更多信息，请 单击此处
