PHP - Trait or Extended Class

Good afternoon guys, I have a trait that formats data on a MVC system , the system works correctly, however I had a question regarding design pattern and performance, of the trait is correct or should you consider extending a Model class instead of using it as trait ?

trait model :

trait Model
{
    function __construct($attributes=array())
    {
        if(sizeof($attributes) > 0){
            foreach ($attributes as $key => $value) {
                $this->$key = $value;
            }
        }
    }

    function __set($name, $value)
    {
        if(in_array($name, self::COLUMN)){
            $this->$name = $value;
        }
    }

    function __get($name)
    {
        if(isset($this->$name)){
            return $this->$name;
        }
    }

    function __unset($name)
    {
        if(isset($this->$name)){
            unset($this->name);
        }
    }
}

user template :

class User 
{
    const COLUMN = array(

        'iduser',
        'name',
        'email',
        'password',
        'permission',
        'status',
        'date_created'

    );

    use Model;
}
