Hi!
Many PHP features should be language constructs, but they were made as
language hacks.
__construct is evil, as like any other language hack
Constructors are standard feature in many languages. There's nothing
evil in them.
class Client {
function __construct() {

It does not provides a safe fundation to build safe abstractions, reusable
and extendibles components, which leads to the lack of PHP libraries.

No, I hadn't seen that. Thanks for pointing this out, it looks like
exactly what I was trying to reinvent...

Hi!
I think the point is that the php language itself does not provide solid
construct for writing rock-solid code. Yes, there are many
programmers/hackers that can, but the effort they put is huge.
I think this is completely untrue.
In Java you are free to extend a class --yours or imported

With objects less copying occurs because the object value (zval) data is
actually just a pointer and an id that for most purposes works as a
pointer.
However, it should be said that while a copy of an array f

programmers/hackers that can, but the effort they put is huge.
it's so easy to break well-written bug-free code, that's impossible for
developers to share libraries,
What about objects?
class Foo {
public $foo;
}
function test($o) {
$o->foo->foo->foo = 2;
}
$bar = new Foo;
$bar->foo = new Foo;
$bar->foo->foo = new Foo;
test( $bar );

Also... is it better to pass an object as a parameter rather than many
values?

Using references does not speed up PHP. It does that already
internally, if I'm not mistaken. The point of my post was that
assigning values to tree arrays are in general faster than a full
array copy.
