I always set error_reporting(E_ALL) oR error_reporting(2047), but i have never got any 
errors when just use empty()  
to determine whether a variable is set.

If the variable is: 0, null, not set or an empty string.
Then the empty() will return true.

It's unnecessary to call isset() first.

Just use empty() ?!

With error_reporting(E_ALL) you'll get a bunch of warnings if you only use
empty() w/o the isset() !

use isset() first and then check wheter empty or not empty!

so there is not one function that tests for empty and isset same time!?
