'" is write-only.');    else      throw new Exception('Property "' . $property .

 title = 'Hello, World';echo $post->title;// The following will throw an exception since $comments is read-only:$post->comments = 23;?>And in case you need a less generic getter or setter at some point, you can remove the variable from the $_getters or $_setters array and implement a method like:
 title = str_replace('World', 'Universe', $value);}?>And from the outside the property could still be used with:
 title = 'Hello, World!';?>

? The above is an example in the manual, but I think it is necessary to first determine whether there is a method for processing attributes in the class. if there is a method, it will be called. if there is no method, it will be set directly.
