never want to use a variable to determine a constant
because the variable is not likely to be the same (that is why we call
them variables) on any iteration. Using constants in expressions is OK,
for instance
if(BAR == $foo){
...stuff...
}

when you define a constant using define() and want to return true/false
is this logical:
if($bars == 3)
{
define('BAR', 1);
}
then:
if(BAR)
{
// bars is true
}
or should i need to do an else statement as
Exactly,
CONSTANTS are ... "eternal truths" to the program, they shouldn't
change, constants should not be changing based on arguments being
passed, or other variables.
by definition, it's no longer a constant, and a misuse of the define
() function.

you could use constants and still sound stupid.
