it's your data - you decide - personally IDGAF. just make sure you santize
your incoming data whatever form you expect it in.

do you know what an if statement is?
have you looked at the manual page for isset()?
do you know what a E_NOTICE is?
the short answer is: difference is 1 line of code,
the longer answer is: read some more of the manual and learn about
error checking (the most simple form being to simply check that a variable
exists before trying to use it.)
