I understand that wanting to update or remove a constant is the exact opposite if what it is meant for, but here is my problem.

I want to be able to format a value in same same fashion that a constant does. i.e.: echo foo;

Where it can just be plain text, instead of echoing a variable like $foo.

It may seem like a silly thing to want to do, but I am hoping to create use out of it. However, if this is not possible, I guess that is that.

PS. I ‘would’ just define it as a constant, however I want it to be able to update (like re-defining it during a foreach).

    Sort of. The first one must be case-insensitive:

    define("myConstant", "blah", true);
print myConstant; // blah
define("myConstant", "xxxx"); // No warning outputted
print myConstant; // xxxx

    But, DON’T DO THIS! The whole point of a constant is that it’s constant. Although you seem to sort of recognize this, what is wrong with that extra $ sign, really, versus a much more clear code style?
