在PHP中访问关联数组

Question

我想在PHP下面的关联数组中访问索引'memo'

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

产量

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

你基本上拥有一组关联数组.所以要访问第一份备忘录,就是这样

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

要访问每个备忘录,您可以执行此类操作

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