[data] => Array
    (
        [0] => Array
            (
                [POL_EXPIREDATE] => 2014-05-19 12:00:00
                [INCO_IWCODE] => 41

But i dont now how to use that data. when i try this :

$b= $json->{1}->{'INCO_IWCODE'};

    Debug::debuger($b);

the result is nothing

what is wrong? sorry for long post.

Answer 1

When setting the second argument on json_decode to true, you are actively asking for the data to be returned in an associative array and not objects. Thats why your code didn't work.

Answer 2

Demo

You are converting json to associative array. You need to use;

$b = $json["data"][1]["INCO_IWCODE"];

Answer 3

$a = $json[0]->INCO_IWCODE;

That worked for my guys. thanks you all!!!
