Problem: Having two collections/MySQL query results and combine them using union():
$result1->union($result2);
then want to remove all duplicate on that union result.
Solution: using unique() to remove duplicates. You can add a parameter like unique(‘id’) to specifically remove which tag name. Example:
$result1 = $result1->unique()->values()->all();
Remember to assign it to a variable or else it will remain the same.
