Hi

What does calling ->registerPHPFunctions() do when it's called more than 
once? Will the existing allow-list be overwritten or amended?

i.e.

$xpath->registerPHPFunctions([
   'strtoupper',
]);
$xpath->registerPHPFunctions([
   'ucfirst',
]);

will I be able to:

(a) Call ucfirst(), but not strtoupper()
(b) Call both

Best regards
