在字符串数组上添加花括号 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

用json_decode($temp, true);解码你的 json json_decode($temp, true);

Answer 2

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}

Answer 3

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));
