text: i want to write cms.!? i want to write or programm cms.using php,mysql i have some q. where should i start? and want do i need in cms. is there any bb code source? thats a good idea but just look at this cms:  http://www.joomla.com/  its very good. writing a good grade cms is a very long and complicated task... definitely not the sort of thing you just wake up in the morning and decide to do. i would recommend any one of these:  http://www.packtpub.com/award   (also check out wordpress on http://wordpress.org/ and dnn.com)  you can write add on modules and extend their core functionality. the also come with source code since they are os. so unless you really are geared towards writing your own or perhaps you just want a small and simple one for which the above are too complicated...  creating a php-based content management system http://www.intranetjournal.com/articles/200407/ij_07_06_04a.html  hope this helps!
