有没有办法在PHP中扩展特征? [英] Is there a way to extend a trait in PHP?

问题描述

我想使用现有trait的功能，并在其顶部创建自己的trait，以便以后将其应用于类.

I want to use functionality of an existing trait and create my own trait on top of it only to later apply it on classes.

我想扩展Laravel SoftDeletes特性以使SaveWithHistory功能，因此它将创建记录的副本作为已删除的记录.我也想用record_made_by_user_id字段扩展它.

I want to extend Laravel SoftDeletes trait to make SaveWithHistory function, so it will create a copy of a record as a deleted record. I also want to extend it with record_made_by_user_id field.

推荐答案

是的.您只需要像这样定义新特征:

Yes, there is. You just have to define new trait like this:

trait MySoftDeletes 
{
    use SoftDeletes {
        SoftDeletes::saveWithHistory as parentSaveWithHistory;
    }

    public function saveWithHistory() {
        $this->parentSaveWithHistory();

        //your implementation
    }
}
