Re: new $foo->className(); Class name must be a valid object or a string

I am trying to load PHP objects stored in a database, where the class name is stored in a column: $object = new $resultSet->getString(1); This fails for the same reason that the following fails: <?php class Foo { public function className() { return 'Foo'; } } $foo = new Foo; $bar = new $foo->className();

I would rather have a factory method that returns a new instance of the class. There's no need for the outside world to know the class name. <?php class Foo {

    public function newInstance()
    {
      return new self();
    }

    public function test($a)
    {
      echo 'test: '.$a."\n";
    }

} $foo = new Foo; $foo->test('foo'); $bar = $foo->newInstance(); $bar->test('bar'); ?> However, if you insist on doing it your way can I make a small suggestion? It's better to spend your time on functionality rather than finding ways to save some typing. I see no reason to try to combine the two statements - saving typing and a pitiful amount of disk space are the only benefits. -Stut -- http://stut.net/
