<?php
    session_start();
    error_reporting(0);
    include("config.php");
    $sql = "select * from category";
    $result = mysqli_query($con,$sql);
    while($row = mysqli_fetch_array($result))
    {
        $data[] = array(
                        'category' => $row['category_name'],
                        'image' => $row['file_s']
                    );

    "category": "cap",
    "image": "Cap-01.png"
  },
  {

    "image": "Hair Color-01.png"
  }
]

But I want it another way like:

[
cap  {
       "image": "Cap-01.png"
     },
hair {
       "image": "Hair Color-01.png"
     }

use category name as index

while ($row = mysqli_fetch_array($result)) {
    $data[$row['category_name']] = array(
        'image' => $row['file_s']
    );
}
echo json_encode($data);
