Question

我如何json_encode第一列名为id，其值为json对象，然后编码其余列，数据为子json对象？我的json是有效

{
    "id"        :"1",
    "first_name":"Henry",
    "last_name" :"Lawrence",
    "email"     :"hlawrence0@storify.com",
    "country"   :"Italy",
    "ip_address":"0.72.132.192"
}

我希望输出如下：

  {
    "id"        :"1"{
    "first_name":"Henry",
    "last_name" :"Lawrence",
    "email"     :"hlawrence0@storify.com",
    "country"   :"Italy",
    "ip_address":"0.72.132.192"
}}
  {
    "id"        :"2"{
    "first_name":"Bonny",
    "last_name" :"Jackson",
    "email"     :"bjdsa0@storify.com",
    "country"   :"Italy",
    "ip_address":"0.72.132.192"
}}

Answer 1

你可以这样做：

$json = '{"id":"1","first_name":"Henry","last_name":"Lawrence","email":"hlawrence0@storify.com","country":"Italy","ip_address":"0.72.132.192"}';
$jsonEncode = json_decode($json, true);
$userArray[array_shift($jsonEncode)] = $jsonEncode;
$result = json_encode($userArray);

试试这个：

<?php

$json = '[{
    "id"        :"1",
    "first_name":"Henry",
    "last_name" :"Lawrence",
    "email"     :"hlawrence0@storify.com",
    "country"   :"Italy",
    "ip_address":"0.72.132.192"
},{
    "id"        :"2",
    "first_name":"Dave",
    "last_name" :"Chen",
    "email"     :"null@null",
    "country"   :"Canada",
    "ip_address":"127.0.0.1"
},{
    "id"        :"4",
    "first_name":"Foo",
    "last_name" :"Bar",
    "email"     :"postmaster@localhost",
    "country"   :"US",
    "ip_address":"0.0.0.0"
}]';

$json = json_decode($json, true);

array_walk($json, function(&$val) {
    $tmp = $val;
    $val = array('id' => $tmp['id']);
    unset($tmp['id']);
    $val['data'] = $tmp;
});

print_r($json);

Output：

Array
(
    [0] => Array
        (
            [id] => 1
            [data] => Array
                (
                    [first_name] => Henry
                    [last_name] => Lawrence
                    [email] => hlawrence0@storify.com
                    [country] => Italy
                    [ip_address] => 0.72.132.192
                )

        )

    [1] => Array
        (
            [id] => 2
            [data] => Array
                (
                    [first_name] => Dave
                    [last_name] => Chen
                    [email] => null@null
                    [country] => Canada
                    [ip_address] => 127.0.0.1
                )

        )

    [2] => Array
        (
            [id] => 4
            [data] => Array
                (
                    [first_name] => Foo
                    [last_name] => Bar
                    [email] => postmaster@localhost
                    [country] => US
                    [ip_address] => 0.0.0.0
                )

        )

)
