Laravel Collections: Filter with two cloumns

So let's just begin with the question.

I have a database with following structure:

id first_user_id  second_user_id
                                                    
1       1           2             
1       2           4			  
1       2           1             

And let's say i have a variable with id=1 $id = 1

I find the needed records with this.

Model::where('status',1)
->where('first_user_id', $id)
->orWhere('second_user_id',$id)->get();

I want to get all of the ids that is not equals to the $id in some of the columns.

For exampe:

if first_user_id is equals to $id
    return second_user_id column
if second_user_id is equals to $id
    return first_user_id column

I want to done that with Laravel Collections if it is possible?

The result must be array with the ids from condition above.

Example output:

Array
(
    [0] => 2 // second_user_id from first record
    [1] => 2 // first_user_id from the last record.
)

For more clearly here is some pseudo php code for what i exactly want

<?php

$students = [
  [
    "first_user_id" => 1,
    "second_user_id" => 2
  ],
    [
    "first_user_id" => 2,
    "second_user_id" => 3
  ],
    [
    "first_user_id" => 1,
    "second_user_id" => 3
  ],
    [
    "first_user_id" => 4,
    "second_user_id" => 6
  ],
];


$var = 2; // Authenticated user
$arr = [];
foreach($students as $student) {
  if($student['first_user_id'] == $var || $student['second_user_id'] == $var) {
    if($student['first_user_id'] == $var) {
      $arr[] = $student['second_user_id'];
    } else $arr[] = $student['first_user_id'];
  }
}

print_r($arr);

Output:

Array
(
    [0] => 1
    [1] => 3
)

Thank you.
