your string is NOT a valid json to start with.

您的字符串不是有效的 json 开始。

a valid json will be,

一个有效的 json 将是，

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

if you do a json_decode, it will yield,

如果你做 a json_decode，它会产生，

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

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

        )

)

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

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

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

you can use json_decodefunction

你可以使用json_decode函数

foreach (json_decode($response) as $area)
{
 print_r($area); // this is your area from json response
}
