convert array to group keys and group values in PHP

Hello I have an array and want to group keys and values as shown below:

[
  "agre" => "0"
  "extr" => "0"
  "inte" => "100"
]

I want to convert it to

{"labels":["agre","extr","inte"],"points":[0,0,100]}

>Solution :

Just create a new array of the keys and the values.

$data = [
    "agre" => "0",
    "extr" => "0",
    "inte" => "100",
];

echo json_encode([
    'labels' => array_keys($data),
    'points' => array_map('intval', array_values($data))
]);

prints

{"labels":["agre","extr","inte"],"points":[0,0,100]}
