the use of the name 'child' is very confusing, I would prefer 'super' or 'static' ...
regardless the concept is actually quite simple:

interface DOInfo {
	static function getTableName();
}

abstract class DataObject implements DOInfo {
	static function findRange() {
		$table = super::getTableName();
		return $foo; // $foo is a collection of whatever (e.g. Product objects)
	}

	static function getTableName() {
		throw new Exception('be a dear and implement '.__METHOD__.' in your subclass'); }

	}

class Product extends DataObject {
	static function getTableName() { return 'PRODS'; }
}

$products = Product::findRange();

excuse me if I've just committed a grave sin against the OO Codex in writing something
that either isn't 'correct' or is syntactically incorrect according to the current
state of php - hopefully the idea is clear anyway.
