Hi, in the first challenge example you wrote:
json_encode('lions', 'tigers', 'bears');
instead of
json_encode(['lions', 'tigers', 'bears']);

Hey Teo,

It depends! Most probably you should iterate over array, as we have an array of pets. So if you decode JSON into the array of objects - do next:


$pets = json_decode($petsJson);
foreach ($pets as $pet) {
    echo $pet->weight;
}

But if you pass "true" for the second argument, you will get array of arrays instead of array of objects, so do it as:


$pets = json_decode($petsJson, true);
foreach ($pets as $pet) {
    echo $pet['weight'];
}

You can always dump variable first to ensure what data it consists, and then you'll be able to get data correctly:


$pets = json_decode($petsJson);
var_dump($pets); die;

Cheers!

`Json` responses looks a really very nice and handy with JSONView Chrome plugin, thanks!
