The PHP documentation says the following about the __call() magic method: __call() is triggered when invoking inaccessible methods in an object context. Is there a way I can have __call() called even when a method exists, before the actual method is called? Or, is there some other hook I can implement or another way that would provide...
Stemming from this question on using __get() and __set() to access private variables, I'd like to get the input on how they are used in general. I am wondering when or where would be the best time to use a overloading function, and where you have used one (if you have). Just to be clear, we are talking about these functions: http://us2....
My situation is best described with a bit of code: class Foo { function bar () { echo "called Foo::bar()"; } } class SubFoo extends Foo { function __call($func) { if ($func == "bar") { echo "intercepted bar()!"; } } } $subFoo = new SubFoo(); // what actually happens: $subFoo->bar();...
Hi there programmers! I'm building a little MVC system (learning) and I have some problems with showing variables in my view files. This is from my View class: private $vars = array(); public function __set($key, $value) { $this->vars[$key] = $value; } public function __get($key) { return $this->...
I just started to use Zend_Amf and thus far I'm really happy with it for sending objects from Flash to the server. Sending my objects from the server back to my Flash environment is causing me a slight headache. My PHP objects mostly contain private properties that have a custom getter and setter method. How do I make Zend_Amf aware of t...

I have a class where I'm using __set. Because I don't want it to set just anything, I have an array of approved variables that it checks before it will actually set a class property. However, on construct, I want the __construct method to set several class properties, some of which are not in the approved list. So when construct happen...
If I have the following registry class: Class registry { private $_vars; public function __construct() { $this->_vars = array(); } public function __set($key, $val) { $this->_vars[$key] = $val; } public function __get($key) { if (isset($this->_vars[$key])) retur...
I've been playing around with Python recently, and one thing I'm finding a bit odd is the extensive use of 'magic methods', e.g. to make its length available an object implements a method def __len__(self) and then it is called when you write len(obj). I was just wondering why objects don't simply define a len(self) method and have it c...

Rails has all sorts of auto-generated methods that I've often times struggled to find documentation for. For example, in routes.rb, if I have: map.resources :projects do |p| p.resources :tasks end This will get a plethora of auto-generate path and url helpers. Where can I find documentation for how to work with these paths? I gener...

Ruby enthusiasts! I am trying to write a DSL in ruby and i would like to be able to create some magic methods (not sure that is the most accurate term for what i want).

Looking to see if there is any way to implement the kind of functionality of the __get() magic method, but when trying to instantiate a new class. My goal is to have $foo = new Cat(); Ultimately result in the creation of a generic object, i.e. new Mammal('Cat'); Such that $foo would be an instance of the class Mammal, with the calle...
I am trying to decorate the magic method __getitem__ to be a classmethod on the class. Here is a sample of what I tried. I don't mind using either classmethod or staticmethod decoration, but I am not too sure how to do it. Here is what I tried: import ConfigParser class Settings(object): _env = None _config = None def __init_...
I have a custom-built MVC PHP framework that I am in the process of rewriting and had a question about performance and magic methods. With the model portion of the framework, I was thinking if __get/__set magic methods would cause too much performance hit to be worth using. I mean accessing (reads and writes) model data is going to be ...
I was writing a class that uses __get() and __set() to store and retrieve array elements in a master array. I had a check to make some elements ungettable, basically to re-create private properties. I noticed that it seemed that __get intercepts all calls to class properties. This sucks for me, because I wanted to have a variable priva...
