如何访问php类中动态定义的属性

Question

trying to develop a class associated with table(like in frameworks). assume we have a class named Book

class Book
{  
  public function save()
  {
     ....
  }

 }

$book = new book;
$book->id = '1';
$book->name = 'some';
$book->save();

the problem is how can i access this dynamically created properties inside save() to save new record

Answer 1

You could do it that way (note that there are other solutions to this problem) :

public function save() {
    $properties = get_object_vars($this);
    print_r($properties);
    // do something with it.
}
