Create aliases for trait methods

You can create aliases for trait methods.
The keyword uses as.

how to use as

  1. trait trait name{}
  2. class class name
  3. {
  4.     use trait name, trait name {
  5.         trait name::method name as alias;

  6.             return 'iPhone';
  7.         }
  8.     }

  10.     trait google
  11.     {
  12.         public function phone()
  13.         {
  14.             return 'pixel';
  15.         }
  16.     }
  17.  
  18.     class people
  19.     {
  20.         use apple, google {
  21.             apple::phone insteadof google;
  22.             google::phone as gp;
