How do you distinguish an object with a "resource" from one not representing such a thing? - Any object? - All internal ones? - Add a class_entry flag? - Hardcode a list? None of those really make sense to me. The `is_*` routines look at PHP's type system, the information for general use is limited (we don't have ReflectionResource as well ... while that couldn't do much anyways as a resource is only a void*) The only use case here seems to be $foo = xml_*(); if (!s_resource($foo)) error(); Which is limited, since the only xml function returning a resource seems to be xml_parser_create() which will always succeed (except out of memory or similar) johannes -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
