At last find stuff to how to solve this issue, i did use "file_get_contents('php://input')" that way i could get POST value in json object and i also decode json value using "json_decode()". So let's try this way :
Example:
$post = file_get_contents('php://input');
$post = json_decode($post);
$sql = "INSERT INTO items (title) VALUES ('".$post->title."')";
$result = $mysqli->query($sql);
