Answer 1

Try using json_decode()
<?php
$sql="SELECT `survey_answers` FROM `user_survey_start`";
if ($result=mysqli_query($con,$sql))
{
while ($row = mysqli_fetch_row($result))
{
$json = $row[0];
$jason_array = json_decode($json,true);
foreach ($jason_array as $data){
$id[] = $data['id'];
$answer[] = $data['answer'];
$type[] = $data['type'];
// here code to insert/update values to db column
}
echo implode(',',$id);
echo implode(',',$answer);
echo implode(',',$type);
}
}
