Find out the balance of the QIWI API wallet?

Question

PHP

I connected this class to work https://github.com/Shnapik/Qiwi-Api-Class-PHP
So, the essence of the matter.
Using the getBalance() method I get the following:

Here is the method code:

public function getBalance() {
        return $this->sendRequest('funding-sources/v2/persons/' . $this->_phone . '/accounts');
    }

Everything corresponds to what is written in the documentation

spoiler

But how can I get only the value of the balance of the wallet, without all the extra stuff. That is, only balance.amount

Answer 1

Do php.net/manual/ru/function.json-decode.php you get a structure from which you take what you need

Answer 2

echo $array['accounts'][0]['balance']['amount'];
