Is there a way to extend trait in PHP?

问题

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

Precisely I want to extend Laravel SoftDeletes trait to make SaveWithHistoryfunction, so it will create a copy of a current state of a record as deleted record. I also want to extend it with record_made_by_user_idfield.

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
    }
}
