Hi @angrybrad, thanks for the PR, it's much appreciated!

Looking at the changes that have been made, do you think it's a better idea to target the PHP version or the libxml version?

I'm thinking libxml as that will also catch anyone that compiles PHP8 with libxml < 2.9.0. What are your thoughts there?

[angrybrad]

@darylldoyle good question. Looks like they recommend either way: https://php.watch/versions/8.0#libxml_disable_entity_loader-deprecation

Not sure how many people would compile PHP with an older version of libxml than 2.9.0, but happy to update to this instead:

if (\LIBXML_VERSION < 20900) {
    libxml_disable_entity_loader(true);
}

Thanks, @angrybrad! I think I'd feel more comfortable targeting the libxml version directly, rather than the PHP version. If you don't mind making that change when you get time, I'll be happy to merge this in 🙂

@darylldoyle done!
