Maybe is isn't as fundamental as you think? I never came across this
problem in years of PHP programming. But then again I use classes with
static calls for nothing but separate namespaces :-)
I'm pretty sure there is another (possibly more elegant) solution. This
is not a flame but a suggestion to rethink the problem you are trying to
solve.

Hi Chris,
I have faced this limitation of the languagee when I was trying to simplify
code which uses Singleton and uses to have n-time the code for caching
copied around. Every new class that one subclass has to copy the code. A bit
overwork, isn't it? At the end we agreed on a solution with __CLASS__ in the
extending classes.
class Foo {
function getInstanceInt($params, $class_name= __CLASS__) {
var_dump($params, $class_name);
/*...*/
}
}
class Bar extends Foo {
function getInstance() {
Foo::getInstanceInt(func_get_args(), __CLASS__);
}
}
$a= Bar::getInstance(1,2,3);
So the getInstance() in the subclasses is quite simple. One also
may declare argument names. Here I haven't done that for simplicity.
Regards,
Andrey
