Adding Curly Braces on Array of String PHP - php

Question

Im looking for the way to add curly braces {} on my Array of string :
print_r(json_encode($temp));
temp = [{"Red":1,"Blue":2,"Green":2}]
Im creating that values with :
$query_final = (my query);
$query = $this->db->query($query_final)->result_array();
$res = array_count_values(array_column($query, 'status'));
array_push($temp, $res);
print_r(json_encode($temp));
become:
print_r(json_encode($temp));
temp = [{"Red": "1"},{"Idle":"2"},{"Overload":"2"}]
So far i've tried to use implode :
$temp = implode(",", $temp);
print_r(json_encode($temp));
but it just giving the error, is there any way to do the right thing ?

Answer 1

array_count_values() returns a list of the values and the number of times they occur, so just using array_push() will add this entire array as 1 item and give you the results your getting.
Instead, you can add the results one at a time to the $temp array and get the results your after...
$temp = [];
$res = array_count_values(array_column($query, 'status'));
foreach ( $res as $key=>$item ) {
$temp[] = [$key => $item];
}
print_r(json_encode($temp));

Answer 2

Decode your json with json_decode($temp, true);

You can use json_encode on an array to get a JSON. Like so:
$temp = ['Red' => 1,
'Blue' => 2,
'Green' => 2
];
print_r(json_encode($temp)); // {"Red":1,"Blue":2,"Green":2}
