SQL query to Eloquent conversion

Question

如何将下面的SQL语句转换为Eloquent？

SELECT * FROM `messages` WHERE (`to`=$myID AND `from`=$guestID) OR (`to`=$guestID AND `from`=$myID)

Answer 1

Use where and orWhere closures for parameter grouping :

Message::where(function($q) use($myId, $guestId) {
    $q->where('to', $myId)->where('from', $guestId);
})
->orWhere(function($q) use($myId, $guestId) {
    $q->where('to', $guestId)->where('from', $myId);
})
->get();
