Assign JSON values to simple variables

Question

I’m having trouble reading a JSON I receive:

{"data":{"charges":{"data":{"charges":[{"code":10006756,"dueDate":"13/09/2014","link":"https://www.teste.com.br"}]},"success":true}

I need to assign these values to my variables, this array will always have 1 record, it’s a rule.

How to get all of his variables (code, dueData, link and success) and assign these values to simple variables? That is in my code I will have:

$code  = valordoJSON;
$dueData    = valordoJSON;
$link  = valordoJSON;
$sucesso    = valordoJSON;

Answer 1

You can use the function json_decode. This function receives a String in JSON format and returns a object or array with the properties of JSON.

Follow a very simple example:

$json = '{"nome": "Bruno", "sobrenome": "da Silva", "idade": "37"}';

//transforma o JSON em um objeto
$objeto = json_decode($json);

echo 'Nome: ' . $objeto->nome;
echo 'Sobrenome: ' . $objeto->sobrenome;
echo 'Idade: ' . $objeto->idade;

If you don’t want an object, you can turn JSON into a array, passing by true as the second function parameter:

$json = '{"nome": "Bruno", "sobrenome": "da Silva", "idade": "37"}';

//transforma o JSON em um array
$array = json_decode($json, true);

echo 'Nome: ' . $array['nome'];
echo 'Sobrenome: ' . $array['sobrenome'];
echo 'Idade: ' . $array['idade'];

Answer 2

it seems that the part {"data":{"charges":{"data":{"charges" is duplicated outside that:

<?php
$obj = json_decode('{"data":{"charges":[{"code":10006756,"dueDate":"13/09/2014","link":"https://www.teste.com.br"}]},"success":true}');

$code  = $obj->data->charges[0]->code;
$dueData = $obj->data->charges[0]->dueDate;
$link = $obj->data->charges[0]->link;
$sucess = $obj->success;

echo $code;
echo $dueData;
echo $link;
echo $sucess;
?>
