提问by horse
I have an $array_variablelike that in my laravel controller:
我的$array_variableLaravel 控制器中有一个类似的：
{"11161":{"total":1,"1":1,"2":0,"3":0,"4":0},"11160":{"total":1,"1":1,"2":0,"3":0,"4":0},"11159":{"total":5,"1":5,"2":0,"3":0,"4":0},"11158":{"total":1,"1":1,"2":0,"3":0,"4":0},"11157":{"total":2,"1":2,"2":0,"3":0,"4":0},"11156":{"total":2,"1":2,"2":0,"3":0,"4":0},"11155":{"total":1,"1":1,"2":0,"3":0,"4":0},"11154":{"total":2,"1":2,"2":0,"3":0,"4":0},"11153":{"total":1,"1":1,"2":0,"3":0,"4":0},"11152":{"total":2,"1":2,"2":0,"3":0,"4":0},"11151":{"total":2,"1":2,"2":0,"3":0,"4":0},"11137":{"total":2,"1":2,"2":0,"3":0,"4":0},"11150":{"total":2,"1":2,"2":0,"3":0,"4":0},"11136":{"total":2,"1":2,"2":0,"3":0,"4":0},"11135":{"total":1,"1":1,"2":0,"3":0,"4":0},"11132":{"total":2,"1":2,"2":0,"3":0,"4":0},"11134":{"total":2,"1":2,"2":0,"3":0,"4":0},"11133":{"total":2,"1":2,"2":0,"3":0,"4":0},"11121":{"total":2,"1":2,"2":0,"3":0,"4":0},"11120":{"total":1,"1":1,"2":0,"3":0,"4":0},"11119":{"total":1,"1":0,"2":1,"3":0,"4":0}}
When I access it in blade file via {{ $array_variable[$id] }}or {{ $array_variable }}, it gives this error:
当我通过{{ $array_variable[$id] }}或在刀片文件中访问它时{{ $array_variable }}，它给出了这个错误：
ErrorException
Array to string conversion
How can I access array elements without error?
如何访问数组元素而不会出错？

When you get $array_variable[$id]it gives you a subquery of:
当你得到$array_variable[$id]它时，它会给你一个子查询：
"total" => [(...)]
which isn't string. So that why you getting this error. The {{ (...) }}statement is for echoing data and when you try to echo array you get this error. You can give a try with something like this:
这不是字符串。所以这就是为什么你会收到这个错误。该{{ (...) }}语句用于回显数据，当您尝试回显数组时，会出现此错误。您可以尝试使用以下方法：
{{ 'total: ' . implode(', ', $array_variable[$id]['total']) }}

It doesn't look like an array, but a json object.. in either case you cannot echo that. What you can do is: json_decode() it and then a for/each loop over it to echo the elements.
它看起来不像一个数组，而是一个 json 对象......在任何一种情况下你都不能回应它。你可以做的是： json_decode() 它然后一个 for/each 循环在它上面回显元素。

use var_dump for printing arrays
使用 var_dump 打印数组
var_dump($array_variable[$id]);
