Answer 1

在for循环中，它显示$quecode和$answer是数组。

在您的SQL语句中，您将这些用作字符串变量。

$sql="INSERT INTO U_ANSWERS(DRMOBILE,ADCODE,DIVCODE,BRDCODE,PRDCODE,ANSWERS,CREATEDON)
        VALUES ('$drmobile', '$quecode', '$divcode', '$brdcode', '$prdcode', '$answer', '$createdon');";

现在可能有两种可能的方式：

将此SQL语句也放在循环中，并插入所有个体这些数组的值（$quecode和$answer）
将这些（$quecode和$answer）数组的值合并为一个字符串（例如逗号）使用implode函数，例如：implode(",", $quecode);，然后按照您现在使用的单个字符串插入。

Answer 2

我认为这个错误是因为你传递了这些数组

 $quecode[$i] = $data[$j]['ANSWERS'][$i]['ADCODE'];
  $answer[$i] = $data[$j]['ANSWERS'][$i]['ANSWER'];

这里：

 VALUES ('$drmobile', '$quecode', '$divcode', '$brdcode', '$prdcode', 
'$answer', '$createdon');

所以应该通过这个：

VALUES ('$drmobile', '$quecode[$i]', '$divcode', '$brdcode', '$prdcode', 
'$answer[$i]', '$createdon');

在php中解析时出现Json插入错误？
