Constants aren't "declare"d, they are "define"d -- declare() is for something else entirely. > > I see where one reply so far identified them as a > "constant." That's PHP's term.

Absolutely they can be used in expressions -- what on earth would be the point of them otherwise? define("TWO", 2); $four = 2*TWO; $four is now 4. > I see where another reply called them "execution > parameters," (which to my mind is just a fancy term for > "constant"). See my first comment -- PHP's execution parameters are something else completely, and are "declare"d, not "define"d! Cheers!
