yippits api PHP json decode

Question

I am trying to loop through and grab details from this response. The "deals" section obviously repeats for however many results there are. I decode the json response with this

$jsonurl = "http://api.yipit.com/v1/deals/?key=&tag=spa";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);

but not entirely sure how to loop with foreach through this ? Any help getting started would be very appreciated!

Answer 1

$json_output->response->deals - array of all deals you recevied. So, you need to iterate through it to get any its info.

e.g. this code will echo all deal descritions:

foreach($json_output->response->deals as $deal)
{
    echo $deal->description.'<br />';
}

[] - means array. It can be iterated using loop. {} - means object(StdClass instance). Its properties accessible via ->.

e.g. deal big image can be retrived just like this(in context of previous foreach loop):

echo $deal->images->image_big;

Answer 2

json_decode() should actually be returning an object to you. In order to access those attributes you can echo $json_output->meta->code to get 200 or $json_output->deals[0]->business->id to get the business id of the first deal. Note the difference between {} and []

I would always recommend using var_dump($json_output) so you can clearly see the object's structure once it has been decoded.
