WHY?
[/snip]
Because the constant can be variable in this case. Consider (this is old
school, and we all know that I am the definition of old school) the
definition of the words themselves...variable and constant. You may want
to use a constant to determine a variable;
$myVar = CONSTANT + 3;
But you would 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...
}
But modifying a constant is a no-no.
