I found this on a zend engine 2 list archive, but didn't see an answer, has
it been resolved? I am trying to create a singleton class heirarchy without
having to override getInstance....
<?php
class Test {
public static function getInstance() {
return new self();
}
}
class Foo extends Test {
}
var_dump(Foo::getInstance());
?>
thekid@friebes:~/devel/php/tests > php5 self.php
object(test)#1 (0) {
}
Expected output would be "object(foo)", so I guess either "self" should
not be evaluated at compile time or this should be disallowed. I'd
prefer the first:)
