This is not true at all: 1. is_dir 2. is_executable 3. is_file 4. is_finite 5. is_infinite 6. is_link 7. is_nan 8. is_readable 9. is_resource (checks the resource's type too) 10. is_uploaded_file 11. is_writable All other `is_*` functions are either checking the type or the instance of an object in some way. -- Richard "Fleshgrinder" Fussenegger -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
