PHP: How to access array element values using array-index

Question

How to access array element values using array-index?

Answer 1

$arr = json_decode($json, true);
foreach ($arr as $key => $value) {
    if (isset($value['pageCount'])) {
        //do something with the page count
    }
}

If the structure is always a single nested JS object:

$obj = current($arr);
echo $obj['pageCount'];
