Building a JSON string with multiple level arrays in PHP

Question

I need this result in PHP:

$pass->setJSON('{
          "formatVersion" : 1,
          "description" : "title",
          "coupon" : {
            "primaryFields" : [
              {
                "key" : "offer",
                "label" : "title",
                "value" : "50%"
              }
            ],
          }           
        }');

I try to build this with arrays:

$jsonpost = array();
$jsonpost['formatVersion'] = '1';
$jsonpost['description'] = "test";

And then convert with JSON_ENCODE:

$json = json_encode($jsonpost);
$pass->setJSON($json);

How do I set the multi level array (coupons) in PHP?

You need to use:

$jsonpost['coupon']['primaryFields'][] = [
'key' => 'offer',
'label' => 'title',
'value' => '50%',
];

Or if you use PHP < 5.4 you should use syntax:

$jsonpost['coupon']['primaryFields'][] = array(
   'key' => 'offer',
   'label' => 'title',
   'value' => '50%',
);

This is because primaryFields in your Json needs to be an array so extra [] as added at the end, and primaryFields is property for coupon object
