Decoding mixture of array and stdObject to Database - php

Question

I am trying to decode a collection of json files to a mysql database and return the decoded values to a datatable for presentation. I have one table called ec2_instances, and want to send to that table an array of values which are located at cfi configuration which works fine. but have now added a new column called aws account id which is on object rather than an array I have updated the model to include the new column but I am struggling

$ret = $matches[0];
foreach ($ret as &$match)
