Very simple, this is being seen as too complicated (in
one of the other posts) so here's an example:
$foo = 'bar';
defined ('FOO', 'bar');
if ($foo == 'bar') {
print "Yep";
}
if (FOO == 'bar') {
print "Yep";
}
See, it's not complicated, both can be used the same
but constants must be scalar AND are "super global",
so, available in all functions.
