Getting twice output in JSON - php

Question

I am using CodeIgniter, I have a form and fields are Employee_name, fromDate, and endDate. I am sending the data to Ajax.(I haven't shared the form code and model code) Now I am displaying the records from database using AJAX and JSON. I am getting the correct output from the database but there is some issue I don't know it's JSON or another issue. I am getting the undefined and then getting my output.
In below image, I am getting the total 9 records from the database which is correct but when I am displaying using JSON then I am getting 18 records. First 9 records undefined and next 9 records my output.
Would you help me out in this issue?

Change the name of the array in foreach from $result[] to results[] and check it.
