Chart.js Convert JSON to PHP array-CodePudding

I am creating a Time Cartesian Chart from Chart.js, I need to get the data as json format, however I need to first generate a php array and use json_encode() in order to get the following json. Does anyone knows what the php array be like inorder to get the following JSON?

            data: [{
                x: '2021-11-06',
                y: 50
            }, {
                x: '2021-11-07',
                y: 60
            }, {
                x: '2021-11-07',
                y: 20
        }]

Thank you very much!

Try this,

$data = [
          [
            'x' => '2021-11-06',
            'y'=> 50
          ],
          [
            'x' => '2022-11-07',
            'y'=> 60
          ],
          [
            'x' => '2023-11-07',
            'y'=> 20
          ]
         ];


$data = json_encode($data);
