Anyway, yes, now you have to register and post one message before gaining full forum access. It certainly is a lot to ask, I know, I am so ruthless and mean. If you want to post a meaningless message, rather than say hello, it's your choice.
Now that you have posted one message, you can ask about your undefined offset issue in the
PhpDig Forums if you want.
