Answer 1

You need to decode the string to a valid array, use json_decode as follows:

$json = json_decode($value, true);
echo $json['username'];

Answer 2

It seems your $data['payment'][0] is json string.So you need to decode it.

Try this way

$value=json_decode($data['payment'][0]->json,true);//second parameter true will return as array. 
echo $value['username'];
