Oh, yes and special methods that you mentioned would come in handy too but from a object perspective. Maybe explicitly calling some sort finalize() method to clean un-referenced objects would also be handy. How does that differ from $x=null; with a reference-counting garbage collector?

When Im talking about something like this would come in handy obviously doesnt work! The paramter null could be added, to get desired result but to be programmatically correct: class MyOverload{ function __construct($Foo) {

       $this->Foo = $Foo;

} // overload the constructor function __construct(String $Foo, String $Bar){

        $this->Foo = $Foo;
        $this->Bar = $Bar;

} public function doSomething(){

       if($this->Foo != null  && $this->Bar == null){
        return $this->Foo . " needs a partner";

// do something with Foo

       }elseif($this->Foo != null && $this->Bar != null){
        return $this->Foo . " and " . $this->Bar . " are partners";

//do

something with Foo and Bar

       }

} private $Foo; private $Bar; } $obj = new MyOverload("Mary"); print $obj->doSomething(); ----- Original Message ----- From: "Hartmut Holzgraefe" <hartmut@php.net> To: "Jakes Potgieter" <jakespotgieter@hotmail.com> Cc: "Stephan Schmidt" <schst@php-tools.net>; <internals@lists.php.net> Sent: Friday, February 27, 2004 4:20 PM Subject: Re: [PHP-DEV] stdClass

It would be nice to have a base class to inherit some special methods as we do in Java.

could you name which ones you think of? being out of the JAVA camp for several years know i no longer know all java.object methods and properties by heart, but PHP mechanisms like __sleep()/__wakeup(), __toString() and the introspection related functions like get_class() and friends should provide comparable behaviour ... (IMHO the fact that any object in JAVA can be casted down to java.object is not that clever after all, and part of it is only due to the fact that there is no other way to have portable container classes, which is now finally solved with generics)

The same as method overloading, one of the most important aspects missing in PHP5 and the new object model.

due to the feature of optional parameters you may end up with more than one overloaded function matching a call signature, due to the fact that argument types in a function call are not known at compile time signature matching would have to happen at runtime, and the language syntax would need to be extended to add parameter type specifiers to function parameter declarations (ok, we already have this one for interfaces ...) -- Hartmut Holzgraefe <hartmut@php.net>
