You can also just do == 0

NULL == 0
array() == 0

Coldshine's method is better though. If you require all the data, make
sure all of the parts have data in them.

Thank you both! So in fact it was ok to do my second option.
What i don't understand is the following:

echo '<br>year: '.($article_year? $article_year: 'null');
echo '<br>month: '.($article_month? $article_month: 'null');
echo '<br>article: '.($article_url? $article_url: 'null');

I know the statements, but what does it look for in this case?
Does it detect wether or not e.g. $article_year is set at all?

Sorry for my empty reply...
Anyways: if a variable is not set, casting it to bool (as done by testing
statements) will result in an E_NOTICE and will return false. Casting a 0 or
a null also return false.

ok, thank you!
I have it up and running now, and tested a lot, and it works great.
Thanks.
