Please post questions etc to the mailing list (php-general@lists.php.net); feature requests to the bug database (http://bugs.php.net). The manual notes system is for submissions of text to be included in the manual; please make sure to read the instructions at http://www.php.net/manual/add-note.php before adding another note. As to your question, I doubt that bitwise operators are used only by the most advanced PHP programmers. For instance, they provide the easiest way to control PHP's error reporting level (See the manual section http://www.php.net/manual/features.error-handling.php) I don't think that bit wrangling could really be described as an 'obscure feature'; many languages have analogous functionality, and the concept involved is one of the basics of computer logic--AFAIK, it's usually covered in any Introduction to Programming-type course. -- +----------------------------------------------------------------+ |Torben Wilson <torben@php.net> Netmill iTech| |http://www.coastnet.com/~torben http://www.netmill.fi| |Ph: 1 250 383-9735 torben@netmill.fi| +----------------------------------------------------------------+
