访问在PHP关联数组 [英] Accessing associative arrays in PHP

问题描述

我要访问索引备忘录在PHP关联数组在下面

  $变量[thelistitems];
的print_r（$变量[thelistitems]）;
 

输出

 阵列
（
    [0] =＆GT;排列
    （
        [产品id] =＆GT; PROD：c6dbdd62-dc13-6421-5a94-c8cd871a59d3
        [备忘录] =＆GT;假
        [征税] =＆GT; 0
        [unitweight] =＆GT; 0
        [unitcost] =＆GT; 450.02
        [单价] =＆GT; 445.02
        [数量] =＆GT; 1
    ）
）
 

解决方案

什么你必须要有具有关联数组的数组。所以访问第一备忘录，这是

  $变量[thelistitems] [0] [备忘录]
 

要访问每个备忘录，你会做这样的事情。

 的foreach（$变量[thelistitems]为$列表项）{
    $备忘录= $列表项[备忘录];
}
 

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
    )
) 

解决方案

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"];
}
