PHP Magic Method: __get () and __set () magical

 _setters) {return $this, $property;    } else if (Method_exists ($this, ' _get_ '. $property)) return Call_user_func (Array ($this, ' _get_ '. $property)); else if (In_array ($property, $this->_getters) OR method_exists ($this, ' _set_ '. $property)) throw new Exception ( ' Property '. $property.    ' Is write-only. '); else throw new Exception (' property '. $property.  ' is not accessible. ');} Public Function __set ($property, $value) {if (In_array ($property, $this->_getters)) {$this, $property = $v    Alue;    } else if (Method_exists ($this, ' _set_ '. $property)) Call_user_func (Array ($this, ' _set_ '. $property), $value); else if (In_array ($property, $this->_setters) OR method_exists ($this, ' _get_ '. $property)) throw new Exception (' property '. $property.    ' Is read-only. '); else throw new Exception (' property '. $property. ' is not accessible. ');}? >this the variables in the $_getters array can be READ from the outside and the variables in the $_setters array can is modified from the outside, like this: 
 title = ' Hello, world '; Echo $post->title;//The following would throw a exception since $comments is read-only: $post-&G T;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 is used with:
 title = ' Hello, world! ';? >

The above is the example in the manual, but I think it should be first to determine whether there is a method of processing the property, some call the method, not directly set the property.
