How to convert array to specific Json format

Question

I have an array that i need to convert to json format

The array is the result of a array_count_values and it looks like this:

(The number of users can change)

array(4) {
  ["user1"]=>
  int(1)
  ["user2"]=>
  int(1)
  ["user3"]=>
  int(1)
  ["user4"]=>
  int(3)
}

and based on that array i need to build a JSON response that must follow this pattern:

$return = [
    ['username' => 'user1', 'accepted' => 1],
    ['username' => 'user2', 'accepted' => 1],
    ['username' => 'user3', 'accepted' => 1],
    ['username' => 'user4', 'accepted' => 3]
];
echo json_encode($return);

I've tried some "foreach" but i struggle a little with arrays and couldn't get it to work.

Answer 1

You can use a foreach loop to get the keys and values from your array to form the output:

$return = array();
foreach ($array as $key => $value) {
    $return[] = array('username' => $key, 'accepted' => $value);
}
echo json_encode($return);
