如何根据laravel中的json值计算分数？

我保存时有这个JSON数据。我在这个JSON中总共有43个数据

"{"question":["1","1","1","1","1","1","1","2","2","3","3","2","2","1","3","2","1","2","3","1","2","3","3","3","2","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3"]}

然后，我尝试使用这个计算来计算这个JSON数据的分数。但它没有计算它，因为我没有得到JSON数据值。我尝试了dd（$survey_score），它总共只有100，因为它只假设所有值都是“1”

所以我的问题是如何在我的Laravel控制器中计算这个JSON值？谢谢大家!

您可以将数据转换为收集

$a = '{"question":["1","1","1","1","1","1","1","2","2","3","3","2","2","1","3","2","1","2","3","1","2","3","3","3","2","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3"]}';

$arr = json_decode($a, true);

echo array_sum($arr['question']);

Output: 83

 $scores = '{"question":["1","1","1","1","1","1","1","2","2","3","3","2","2","1","3","2","1","2","3","1","2","3","3","3","2","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3"]}';
$arr = json_decode($scores, true);
$result = collect($arr['question'])->sum();

Output: 83

试试这个，它会起作用的：

$a = '{"question":["1","1","1","1","1","1","1","2","2","3","3","2","2","1","3","2","1","2","3","1","2","3","3","3","2","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3"]}';

$a = json_decode($a, true);

$sum = 0;
foreach($a['question'] as $key => $value){
     $sum += $value;
}

echo $sum; // 83

以上代码已经过测试，谢谢您的帮助！我尝试你的代码，它的工作！

$a = '{"question":["1","1","1","1","1","1","1","2","2","3","3","2","2","1","3","2","1","2","3","1","2","3","3","3","2","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3","1","2","3"]}';

$a = json_decode($a, true);

$sum = 0;
foreach($a['question'] as $key => $value){
     $sum += $value;
}

echo $sum; // 83
