需要帮助解析php中的字符串

Question

您好我正在尝试从PHP中的字符串处理和读取/解析数据。 var转储时的字符串看起来像这样

@Html.DropDownList("Status", (SelectList)ViewBag.NominationStatuses)

我希望能够存储

string(266) "{ "address": { "address_line1": "2391 US HIGHWAY 22 W", "address_line2": "", "address_city": "UNION", "address_state": "NJ", "address_zip": "07083-8517", "address_country": "US", "object": "address" } }" ，address_line1，address_line2，address_city，address_state和address_zip变量，以便我可以随意操作它们。< / p>

我该怎么做呢。

感谢您的时间。

Answer 1

您必须使用json_decode()功能来检索您的数据：

$input = '{ "address": { "address_line1": "2391 US HIGHWAY 22 W", "address_line2": "", "address_city": "UNION", "address_state": "NJ", "address_zip": "07083-8517", "address_country": "US", "object": "address" } }';
$result = json_decode($input, true);

var_dump($result); // see whole array

echo $result['address']['address_line1']; // specific data

您可以从manual获取更多信息。

您可以使用以下指令将字符串转换为JSON

$obj = json_decode($json);

然后您可以从JSON获取值，如下所示

$obj->address->address_line1;
