Real properties in PHP

I wrote about real properies a few days ago but no one seems to be
interested in it.

I think that it would be nice to have real properties present in PHP. I
mean properties like those in C# but a little more flexible by allowing
getter and setter to have different visibility. See sample code below:

Sample code:

class person {
public $firstName, $lastName;

public getter fullName { // may also have ()
return "{$this->firstName} {$this->lastName}";
}

public setter fullName ($value) { // may also not have ($value) but
a special var.
list ($this->firstName, $this->lastName) = explode (' ', $value, 2);
}
}

$p = new person;
$p->fullName = "Foo bar";
echo $p->firstName . "\n";
echo $p->lastName . "\n";
echo $p->fullName . "\n";

Sample result:

Foo
bar
Foo bar

public setter fullName ($value) { // may also not have ($value) but

list ($this->firstName, $this->lastName) = explode (' ', $value, 2);
}

This can be easily done with

function _get($name)
{
$get = "get$name";

     return $this->$get();

}

function _set($name, $value)
{
$set = "set$name";

     $this->$set($value);

}

in your base class (the function names are then get_fullName/set_fullName.

I know this solutions but it does not solve the property visibility
issues and good overloading rules like in common methods. Let's say
you have about 6-7 suche proterties which you expect to overload and
some of the are private e.t.c

But that has plenty of problems, like I described here:

I very much like your idea and syntax. I come from a Delphi background (when
it comes to properties) and I must say I like your solution. It's easy and
effective. Yes, it can be done with __set() and __get(), but it sure is
uglier when you have a wide and constant range of properties.

+1 (with 0 karma anyway).
