PHP - cant get value with json_decode

The API is:

{"status":1,"data":[{"address":"0x5c48aebbbbdcf44f5f181edbb5b20a68210eacfe","balance":6000000000000000000,"nonce":null,"code":"0x","name":null,"storage":null,"firstSeen":null}]}

I am trying to get the value from Balance (6000000000000000000). I also need to divide this value with 1000000000000000000 in meantime...

I tried:

$obj = json_decode($json,true);
$address = $obj['address'];

$json = file_get_html('https://etherchain.org/api/account/'.$address);
$obj = json_decode($json);
$v = (get_object_vars($obj->data));
$balance = $v['balance'];
$_SESSION['balance'] = $balance;

It doesn't work.

The same code works with the API below:

{"status":"success","data":{"address":"LU4P8fVNj8xv2dwRc7fdXmpaW2xuCSJvUK","is_unknown":false,"balance":0,"balance_multisig":0,"totalreceived":0.0340576,"nb_txs":11,"first_tx":{"time_utc":"2015-08-30T09:51:05Z","tx":"10f4b55d0bead8d3d84fe27433db20b63368d65bc043c651d59dbe1342d14098","block_nb":"842330","value":0.00704229,"confirmations":251241},"last_tx":{"time_utc":"2016-02-02T16:09:23Z","tx":"c666d3acf6f57fd86a2ccc9537ee022167da408f26193e4abbd7b8148fc518b3","block_nb":"932771","value":-0.01250452,"confirmations":160800},"is_valid":true},"code":200,"message":""}

What am I doing wrong?

Its because you're missing that the address is located in the first data array in the JSON string and in the second JSON string, no array exists inside the data array.

$obj = json_decode($json,true);
$address = $obj['data'][0]['address'];
$json = file_get_contents('https://etherchain.org/api/account/'.$address);
$obj = json_decode($json);
echo $obj->data[0]->balance;
