[FX.php List] PHP Notices OK?

I'd agree with those who recommend finding the cause of the notices  
and fixing it.

In my experience, it's most often been from undeclared variables; PHP  
4 doesn't require it, if I understand correctly, while PHP 5 does.  
I've been bitten by that when moving a solution to another host other  
than my own servers.
