Actually, there is a way, to (re)declare FALSE (also: False, false, TRUE, NULL, etc.) constant, even
if it is already declared:
<?php
var_dump(constant('I_DONT_EXIST')); // warning "Couldn't find constant
I_DONT_EXIST"
var_dump(constant('FALSE')); //no warning, output: bool(false)
define('FALSE', TRUE);
var_dump(constant('FALSE')); //output: bool(true)
// but...
var_dump(constant('false')); // output: bool(false)
var_dump(FALSE); // output: bool(false);
?>
