Answer 1

if your array is ['img1.jpg','img2.jpg','img3.jpg'] then you should use below code

<?php
    $images = ['img1.jpg','img2.jpg','img3.jpg'];
    foreach($images as $key=>$image){
      $images['ad'.($key+1)] = $images[$key];
      unset($images[$key]);
    }
    print_r(json_encode($images));
?>

Answer 2

$arr = [];
for ($i=0;$i<count($image); $i++) {
    $arr['ad'.$i+1] = $image[$i];
}
$settings = json_encode($arr);
print $settings;
