Hello,

I want to access the index 'memo' in the associative array in PHP below

$variables["thelistitems"];
print_r($variables["thelistitems"]);

Output

Array
(
    [0] => Array
    (
        [productid] => prod:c6dbdd62-dc13-6421-5a94-c8cd871a59d3 
        [memo] => dummy 
        [taxable] => 0 
        [unitweight] => 0 
        [unitcost] => 450.02 
        [unitprice] => 445.02 
        [quantity] => 1
    )
) 

Answer 1

Do you want this ?

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

Answer 2

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"];
}
