Read Json with php, some troubles

Question

I have tried, checked many previous topics, and i cant find the way. Parsing JSON with PHP There is the answer, but im blind; actually, im a medimu PHP programmer, but im new with Json.

Here is my Json:

{"result":"true","disponible":{"aaa":"0.00001362","bbb":"0.000392","ccc":"0.00788523","ddd":"0.00004443","eee":"0.0001755","fff":"0.1755","ggg":"797.64618376"}}

My code:

$balances = json_encode(get_balances(),true);
print_r($balances);

The screen show my Json, so everything is ok here. Now, i want take the bolded values from the json and assign it to PHP variables.

$variable1 = $balances["disponible"]["bbb"];
$variable2 = $balances["disponible"]["ggg"];

echo "Valor 1: ".$variable1 ."<br>";
echo "Valor 2: ";$variable2 ;

But it dont work. I tried with many combinantions and nothing. What im doing wrong?

Thanks a lot in advance. Im blocked with this.

`json_encode` __encodes__ to json. And you need __decode__ from json. — u_mulder, Dec 23 '17 at 20:37
It's unclear what get_balances() returns in your example, but it seems you need to be using json_decode() to access the data via PHP — djt, Dec 23 '17 at 20:38
Can't you just use the return of `get_balances()` instead of encoding it to json? Assuming you are receiving the json in another script, you'd want to `json_decode` before using it as an array/object. — Douglas Santos, Dec 23 '17 at 20:38
Get_balances returns the data "as is" (json format) from a web server. So i need decode it before assign variables? — Pedro Jose Otero Rodriguez, Dec 23 '17 at 20:42
If `get_balances()` returns json you don't need to encode it. Simply decode the return value and you're good. — Douglas Santos, Dec 23 '17 at 20:46
As i explained in the other answer, it do not worked (not at least in the "obvious" way i did) — Pedro Jose Otero Rodriguez, Dec 23 '17 at 20:53

Replace: $balances = json_encode(get_balances(),true); with: $balances = json_decode(get_balances(),true); if you are trying to get associative array.

i got this: "Warning: json_decode() expects parameter 1 to be string, array given in...." I already tried it before i posted here. – Pedro Jose Otero Rodriguez Dec 23 '17 at 20:52
@Pedro Well… that means `get_balances()` **already returns an array.** There's no JSON involved here apparently. – deceze Dec 23 '17 at 20:58
I just readed in the API documentation that they returns a decoded Json file, not a json itself. Thanks. 2 days lost for not read the documentation. – Pedro Jose Otero Rodriguez Dec 23 '17 at 21:07
