What you essentially have is an array of associative arrays. So to access the first memo, it's
您本质上拥有的是一组关联数组。所以要访问第一个备忘录，它是
$variables["thelistitems"][0]["memo"]
To access each memo, you'd do something like this
要访问每个备忘录，您可以执行以下操作
foreach($variables["thelistitems"] as $listitem) {
$memo = $listitem["memo"];
}
