Accessing associative arrays in PHP

What you essentially have is an array of associative arrays. So to access the first memo, it's

 $variables["thelistitems"][0]["memo"]

To access each memo, you'd do something like this

foreach($variables["thelistitems"] as $listitem) {
    $memo = $listitem["memo"];
}

Do you want this ?

$variables["thelistitems"][0]['memo']
