First you decode the string using json_decode, the second argument means that the function should return an associative array and non an array of objects. This willl help up get the array keys.
$decoded = json_decode($var, true);
You get the array keys with this loop and place them in $var
foreach($decoded as $key => $value){
$var2[] = $key;
}

As i comment, use array_keys, and json_decode.
I don't believe that this question has an answer, So i did't answer it. But i did it later.
You have an json, so you need to use json_decode now you jave an array where your keys are the desired value. so use array_keys.
$var = '{"4":true,"6":true,"8":true}';
$arr = json_decode($var, true);
echo '<pre>';
print_r(array_keys($arr));
Result:
Array
(
[0] => 4
[1] => 6
[2] => 8
)
