A note on redefining:
Constants can't be redefined:
$ php -r "define('A', 1); var_dump('A'); define('A', 2);
var_dump('A');";
string(1) "A"
PHP Notice: Constant A already defined in Command line code on line 1
string(1) "A"
But using the case insensitive setting shows that the internal
representation is lower case:
$ php -r "define('A', 1, true); var_dump('A'); define('A', 2);
var_dump('A');";
string(1) "A"
string(1) "A"
Note the lower case 'a' in the second define() here:
$ php -r "define('A', 1, true); var_dump('A'); define('a', 2);
var_dump('A');";
string(1) "A"
PHP Notice: Constant a already defined in Command line code on line 1
string(1) "A"
(Short version: Yes, but no)
