Krishna, I think what you'd LIKE to do, isn't really what the language builders intended (i.e. extending the language itself with your own class(es))... so that you don't have to use 'include' statements. There might be something on the php site regarding a software developers kit or something along that lines, but I haven't really looked. There's, however, nothing that says you CAN'T centrally locate your common classes in one location... and then just INCLUDE them in your php routines. If you write your code correctly, you should only need to put the 'include' statement, for your common class(es), in one place... per module/website. Larr.
