Question

我试图传递$ data数组以将其保存在laravel存储文件中我的代码是：

$data = '[
            {
                "label": " Total Accidents",
                "color": "#5ab1ef",
                "data": 
                    [
                        ["Jan",0],
                        ["Feb",0],
                        ["Mar",0],
                        ["Apr",0],
                        ["May",0],
                        ["Jun",0],
                        ["Jul",0],
                        ["Aug",0],
                        ["Sep",0]
                    ]
            },
            {
                "label": " Active Experts",
                "color": "#f5994e",
                "data": 
                    [
                        ["Jan",0],
                        ["Feb",0],
                        ["Mar",0],
                        ["Apr",0],
                        ["May",0],
                        ["Jun",0],
                        ["Jul",0],
                        ["Aug",0],
                        ["Sep",0]
                    ]
            },
            {
                "label": " Pending Payments",
                "color": "#d87a80",
                "data": 
                    [
                        ["Jan",0],
                        ["Feb",0],
                        ["Mar",0],
                        ["Apr",0],
                        ["May",0],
                        ["Jun",0],
                        ["Jul",0],
                        ["Aug",0],
                        ["Sep",0]
                    ]
            }

      ]';   
 $test = json_decode($data, true);
 $test[0]['data'][1] =  ["Jan", 153];
 Storage::disk('chartData')
    ->put('chart/test'.$_SESSION['companyId'].'.json', $test);
 return 'done';

我想根据数据库值更改每年内的值，问题是当iam尝试将方法iam收到以下错误时：

数组到字符串转换

如果我在没有执行json_decode的情况下传递$ data数组它工作正常，但在这种情况下我不能更改数据是否在数组中，所以我必须解码它。

在这种情况下，您应该使用json_encode函数将JSON数据转换为字符串。

$test[0]['data'][1] =  ["Jan", 153];

$test = json_encode($test);// convert to string

Storage::disk('chartData')
->put('chart/test'.$_SESSION['companyId'].'.json', $test);

在laravel php的put存储方法中传递json数组表单
