  1. Hi,
    Sorry, i forgot to mention about the programming language and the type of variable used here.

    Its for the php and joomla programmers (these are software languages). this code will help you find the next registration number of users. for example you have a software to register users(like student, customers of your shoap, etc). And want the system should generate the registeration number of the user. then the above code will do that for you.
