PHP: How to add value to array within foreach

Question

I have the following array:

$cards = array();
foreach($cardList as $card) {
  if ($card->getIsActive()) {
    $myValue = 'my_value';
    $cards[] = $card->getData(); // need to add $myValue to $card data
  }
}

$result = array(
    'cards' => $cards
);
echo json_encode($result);

How would I be able to add $myValue to $card->getData() so it appears in my $result ?

@JayBlanchard I edited my question a little bit to hopefully clear it up. I can parse the JSON, I'm more asking how to add a value to an existing array of data so it can be parsed by json. — AJK

Basically what you need to is: $card['my_value'] = $myValue inside of the loop — Bruno Francisco

One method is to add the value to the correct part of the object.

$cards = [];
foreach($cardList as $card) {
    if ($card->getIsActive()) {
        $myValue = 'my_value';
        /***
         * Add the data to the object
         ***/
        $card->addData($myValue);
        $cards[] = $card->getData(); // need to add $myValue to $card data
        /***
         * You do NOT need to remove this added data because $card is 
         * simply a COPY of the original object.
         ***/ 
    }
}

There are lots of possible method, depending on what restrictions you have in place for how you can read the data....

Thanks! I ended up adding $card['my_value'] = $myValue before $card->getData() , but this worked as well!
