I prefer the first solution since it's clear which parts are handled as variable-names and which are handled as test. Mixing text and variables (evaluation of variable names "inside" a string does work - but in my oppinion it makes the sourcecode less readable, manageable and leads to more errors.
With the var-in-string-solution there are also other drawbacks like problems with syntax highlighting etc.
Hehe - one funny example - what output do you expect?
echo $a-$b;
echo "$a-$b";
:-))
Hehe true.
Ok, i prefer the first one as well. I was just wondering ;)
I didn't expect so many answers so fast :)
thanks guys !
