PHP总结JSON对象值 [英] PHP Sum up JSON Object value

问题描述

我知道这听起来很愚蠢，但是如何获得所有对象总数的总和?

I know this sounds silly but how do I get the total sum of all the object's total?

我的json解码格式如下:

My json decode format looks something like this:

Array
(
[results] => Array
    (
        [0] => Array
            (
                [total] => 22   
            )
        [1] => Array
            ( 
                [total] => 10
            )
     )
)   

我尝试使用类似这样的方式写，但是它显示试图在...中获取非对象的属性"

I've tried using writing something like this but it shows "Trying to get property of non-object in..."

echo 'Array Total<pre>';
$sum = 0;
foreach ( $receipt_data['results'] as $receipt )
{
    $sum += $receipt->total;
}
echo '</pre>';

推荐答案

试试看，它对您有用 您有数组，因此需要使用数组而不是对象.

Try this it's works for you You have array so you need to use array instead of object.

echo 'Array Total<pre>';
$sum = 0;
foreach ( $receipt_data['results'] as $receipt )
{
    $sum += $receipt['total'];
}
echo '</pre>';
