IMO: memzero is fine; memcmp isn't that great.
memzero() stands out as unusual and interesting because PHP scripts
don't usually get to manipulate memory, only variables. From the "Using"
guide
void \Sodium\memzero(&string $secret);
it looks like it's for zeroing strings.
What arg types does memzero() work with?
Does it check argument type?
Is it safe to use with opcache? Interned strings is an interesting case
but there might be others.
