php return json encoded string from function

Question

One of my functions is returning json encoded content using:

return json_encode($json, true);

Now in my code, calling this function I've already tried to use:

die(var_dump($result[0]));
die(var_dump($result["user"]));
die(var_dump($result->user));

None of this worked. When I dump the whole content I get returned, this is the output:

{"usd":1,"user":10000}

Answer 1

I am assuming that the $result variable is the content that is returned from the function.

You cannot access the properties inside that json string, before you decode it again. Therefore you will not be able to use $result["user"] or $result->user as the result contains a json string.

You need to decode it first:

$result = json_decode($result, true);
