如何用Laravel术语编写PHP SQL查询

Question

How would I write this php mysql query in laravel's terms. I've checked the documentation and cannot find an IF or AS in there documentation for SQL in Laravel 4.2

This is the php query:

query("SELECT IF(friends.sender = ".$_SESSION["user"].", friends.recipient, friends.sender) AS user_id FROM friends WHERE friends.status=1 AND friends.sender = ".$_SESSION["user"]." OR friends.recipient = ".$_SESSION["user"]." AND friends.status=1 ")

I'm trying to format it like this,

@foreach(Friends::if("sender","=",Auth::user()->id)->as("user_id")->where("status","=",1)->where("sender","=",Auth::user()->id)->orWhere("recipient","=",Auth::user()->id)->where()->get() as $user_friends)

You can use Query builder or Eloquent to do that

With Eloquent (this code will be added to the controller)

public function getFriends($arg1, $arg2)
{
  $friends = Frind::where('filed-name', 'operator', $arg1)->where('filed-name', 'operator', $arg2)->all();
  return view('/view-name', ['friends' => $friends];
}

or with Query Builder

public function getFriends($arg1, $arg2)
{
  $friends = DB::table('friends')->select('friends.*')->where('filed-name', 'operator', $arg1)->where('filed-name', 'operator', $arg2)->get();
  return view('/view-name', ['friends' => $friends];
}
