PHP Traits: How to resolve a property name conflic

问题:

How to resolve a property name conflict when a class uses two Traits with homonymous properties?

Example:

<?php

trait Video {
    public $name = 'v';
}


trait Audio {

    public $name = 'a';
}


class Media {
    use Audio, Video;
}

$media = new Media();
$media->name;

I've tried insteadof (Video::name insteadof Audio) and (Video::name as name2) without success.

Thanks in advance !

You can't, its for methods only.
However they may use the same property name only if the value is the same:

trait Video {
  public $name;
  function getName(){
    return 'Video';
  }
}
trait Audio {
  public $name;
  function getName(){
    return 'Audio';
  }
}
class Media {
  use Audio, Video {
    Video::getName insteadof Audio;
  }

  function __construct(){
    $this->name = $this->getName(); // 'Video'
  }
}
