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.
