Thank you all for your replies. The issue was "solved" for a better fitting solution on this case, that was by using a regex expression.
I've not tested the difference between using == or ===. I was using ! But, the main question that is not clear on my newbie head is, "why how why" couldn't this 0 be interpreted, neither as octal, or false, or whatever it may be, but as just a humble numeric value of 0. At least on the cases where FILTER_VALIDADE_INT is there. Anyway, I cannot dig in into this because I'm actually unable to offer some solutions. So, as stated, the issue was solved, by using a regex, so all good here. ;) Thanks once again, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
