CurlHandle and CurlMultiHandle are castable to int in php8

[xPaw]

php/php-src#5743

I'm not sure where I would apply this change in phpstan, so creating this issue instead. As I was testing the new phpstan release, spotted this.

PHP8 allows casting these to ints to preserve backwards compatibility.

Thank you for letting me know, but I think it's better to notify the user about this so that they're aware this is no longer a resource, rather than implementing this unique "object castable to integer" semantics...

Well, it is a useful mechanism, which is why php8 added this in the first place, as plenty of codebases use this. Namely composer and symphony.

It's especially useful when doing multi curl, to keep track of curl handles in an array.

What would be an object-first alternative? spl_object_hash?

[xPaw]

spl_object_id I guess.
