php4 objects

[Robby Russell <robby@xxxxxxxxxxxxxxx>]

A friend of mine asked me if I knew if this was possible in PHP4.


class foo
{
    var $bar = NULL;

    function foo()
    {
        $this->bar = new bar();
    }

    function getBar()
    {
        return $this->bar;
    }

}


class bar
{
    var $thing = NULL;

    function bar()
    {
        $this->thing = "Hello World!";
    }

    function getThing()
    {
        return $this->thing;
    }

}


he wants to do something like this:

$obj =& new foo;

print $foo->getBar()->getThing();

is this possible in PHP4?

I know that he can do a:

print $obj->bar->getThing();

..but he wants it to run some stuff in the functions that he is calling
and wants to do it in one command if possible.
