I'm working on simple PHP Commenting system & I need to add CAPTCHA & Simple BBCode with Smilies
so any recommendations please ?!

For the CAPTHCA system, how about this?

I've used it myself and like it alot. It's rather easy to use and to configure.

BBCode is probably done best with regular expressions.
This would be the RegEx to replace
[b ]*text*[ /b] with <b>*text*</b>:

PHP Code:

<?php
echo preg_replace(
"/\[b\](.*)\[\/b\]/",   //RegEx Pattern, this looks really weird but that's because many characters need to be escaped
"<b>$1</b>",           //Replacement, $1 stands for the first subpattern (which you can define in the pattern by: "(more pattern)"
"[b]*Text*[/b]");      //String to be processed
?>

Thanks lizciz for the CAPTCHA & Thanks Insensus for the BB too, But I need Javascript buttons the user can use it , not to write the BBCode manually

have you tryed tinyMCE ?
if you want to insert only bbcode you could have a look at this tutorial :

It sound to me that you want a WYSIWYG editor. Check this out
