Sorry for that. I didn't know anyhing about interfaces until I had to seek
for a solution for lacking of multiple inheritance.
I'll keep silent to accept what php5 can give me. Just one last question:
How, using php5 interfaces, can one avoid implementing method 'doit'
twice? Thanks.
class foo {...}
class bar {...}
class foobar {
function doit()
{
echo "doing it.";
}
}
class f extends foo, foobar {...}
class b extends bar, foobar {...}
