PHP5 is awsome. ------------------------------------------------------------------------ [2004-09-26 20:39:39] helly@php.net Your last complain is fixed too: marcus@frodo /usr/src/PHP_5_0 $ php -r 'interface foo{function bar();} class baz implements foo{}' make: `sapi/cli/php' is up to date. Fatal error: Class baz contains 1 abstract methods and must therefore be declared abstract (foo::bar) in Command line code on line 1 marcus@frodo /usr/src/PHP_5_0 $ php -v make: `sapi/cli/php' is up to date.

However, in the example above, if foo() is not implemented in class c, no compile error is thrown. The developer must instantiate the class prior to knowing it is abstract. This forces the developer to manually ensure that all abstract members from higher up in an inheritence heirarchy have been implemented. ------------------------------------------------------------------------ [2004-09-25 20:16:06] bobalong at gmx dot net Cool, and I'm sure that's not at the top of the priority list.
