How to convert JSON to Array by PHP

Question

I have following JSON data received.

{
    "app": "000",
    "members":[
        {
            "name":{
                "value": "PIYO"
            },
            "email":{
                "value": "piyo@alk.jp"
            }
        },
        {
            "name":{
                "value": "HOGE"
            },
            "email":{
                "value": "hoge@alk.jp"
            }
        }
    ]
}

I would like to convert it to following array.

[["name" => "PIYO", "email" => "piyo@alk.jp"], ["name" => "HOGE", "email" => "hoge@alk.jp"]]

How can I handle it? Please give me some advice.

You could use

$array = json_decode($json, true);

Don't forget that $json must be in string.

I tried to test result on PHP.

<?php
$json = '{
    "app": "000",
    "members":[
        {
            "name":{
                "value": "PIYO"
            },
            "email":{
                "value": "piyo@alk.jp"
            }
        },
        {
            "name":{
                "value": "HOGE"
            },
            "email":{
                "value": "hoge@alk.jp"
            }
        }
    ]
}';

$array = json_decode($json, true);

print_r($array['members']);

Result:

Array
(
    [0] => Array
        (
            [name] => Array
                (
                    [value] => PIYO
                )

            [email] => Array
                (
                    [value] => piyo@alk.jp
                )

        )

    [1] => Array
        (
            [name] => Array
                (
                    [value] => HOGE
                )

            [email] => Array
                (
                    [value] => hoge@alk.jp
                )

        )

)

Your answer would be better if you explained how and why this affects the problem at hand. Simply dumping code is less likely to help the OP and any inexperienced future readers as well. @Danial No, it wouldn't. The second parameter (`true`) specifies that the JSON should be converted as an associative array. – El_Vanja Dec 11 '20 at 15:44

$foo = json_decode($json,true);
$members = $foo['members'];

$members will be the array you want.

I have error 'ErrorException: json_decode() expects parameter 1 to be string, array given in file' . Please give me an advice. – tajihiro Dec 11 '20 at 05:51
Im "assuming" you're assigning your json string to $json. – Danial Dec 11 '20 at 05:57
This would still produce an array of stdClass objects, which is not the goal OP specifies. – El_Vanja Dec 11 '20 at 10:51
Late night helping is discouraged. I prefer objects; an array of objects is what I'd want in this case. – Danial Dec 11 '20 at 16:46
