   $this->config = "get file";
}
}

class a extends parent {

Answer 1

Just define a function inside your parent class, that returns you your config:

abstract class parent
{

   private config;

   public function __construct()
   {
      $this->config = "get file";
   }

   public function getConfig(){
      return $this->config;
   }

}

class a extends parent
{

   private config;

   public function __construct(){
      $this->config = parent::getConfig();
   }

}
