Anyway, IMO, moving resources from HashTable to a plain C array is a good thing. Allocating segments of 20 structs, for instance, would be fine as a single segment would fit 99.9 % of the cases. This way, you could even compute a pseudo resource handle from the zend_resource address (for var_dump()). The only additional thing you would need is a field to mark the resource as deleted/invalid. But setting ptr to NULL and type to -1 would be probably enough. I am interested in the subject of resources because I just implemented a resource abstraction layer in php-ext-gen (https://github.com/flaupretre/php-ext-gen). The objective being to use the same user code for PHP 5 and 7. Maybe you can have a look at the project and give me your opinion.
