Hi!
In Child $foo is redefined without a getter-method. This breaks theHow it's not "in Child the get method is inherited from Mother"? But suppose it is as you say. Yes, in this particular case it would be detected - however, it is not the code you brought in the last example, where the actual code - not method presence - was changed. Summarily, LSP can not be *enforced* by language means. The language can only give support for some limited subset of cases. PHP's get/set handlers allow you to do the same as your property syntax and more, albeit with different syntax. -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
