Problem with json in while?

Question

PHP

In a loop I collect files. I need to return it in JSON in this format:
{"1":"d.txt","2":"dj.txt"}
But it comes out like this:
{"1":"d.txt"}{"2":"dj.txt"}
Here is the code:

<?
$files = array_diff(scandir("plug/lol/"), ['.','..']);
$lole = [
"count" => count($files)
];
//echo json_encode($lole);
foreach($files as $key=>$lol){
    $result = [
    $key-1=> $lol
    ];
    echo json_encode($result);
}
?>

Answer 1

and where do you have the while promised in the header?
why output a new array each time inside the loop, instead of creating a GENERAL one? etc. )))))
