A #PHP global constant redefinition is a simple warning.

A #PHP class constant redefinition is a full Fatal Error.

I am so used to the Fatal error, that I expected the global constant to behave the same. Shouldn't they?

@pollita @dseguy it used to be a notice in PHP 7 and was elevated to a warning in 8.

I'm sure we will just have another round of elevating warnings to errors in PHP 9.
