Question

could anyone here help me with php an decoding json? Im trying to decode a json api url

Here is what I have at the moment:

  $string = '
    {
        "username": "someusername",
        "unconfirmed_reward": "0.08681793",
        "send_threshold": "0.01000000",
        "confirmed_reward": "0.02511418",
         "workers":
        {
        "bitcoinjol.jason-laptop": {"last_share": 1307389634, "score": "0", "hashrate": 0, "shares": 0, "alive": false},
        "bitcoinjol.david-laptop": {"last_share": 1307443495, "score": "1.7742", "hashrate": 24, "shares": 1, "alive": true},
        "bitcoinjol.pierre-pc": {"last_share": 1307441804, "score": "0", "hashrate": 0, "shares": 0, "alive": true},
        "bitcoinjol.testJol": {"last_share": 0, "score": "0", "hashrate": 0, "shares": 0, "alive": false}
        },
        "wallet": "asdasdjsadajdasjdsajasjdajdajs",
        "estimated_reward": "0.00131061"
    }';

    $json_o = json_decode($string);
    echo $json_o->username;

and this prints out “someusername” but I cant get it to print out the workers when I try:

echo $json_o->workers->someusername.jason-laptop;

I think that the “.” or the “-” I am using are invalid?

I would like to be able to print out each worker and then the waller, username and rewards ect..
using arrays or these objects, either way. I have also tried splitting the $String on “,” with explode, but cant get that to work nicely either.

running Server 2008 R2 with php 5.3 and IIS 7.5

You can use the curly brackets syntax suggested by Gumbo:

$json_o->workers->{"someusername.jason-laptop"}

However, the best way (imo, for consistency) is to use the resulting object as an associative array:

$object = json_decode($string, true);

$object['workers']['bitcoinjol.jason-laptop']['last_share']; // 1307389634
