Another thread sparked an interest:
With using BBCode, do you have to install that package or is it the browser that recognises it? I would like to make my own for my website to let certain users edit the code (without needing to know html) and so I was just wondering where I should look. Most of the links refer to phpBB forums, but this will be using my own code on my site.
Alternatively, if this is not available, do any of you know a good free html filter (which is basically what BBCode is I believe)?

You can install it, or create your own. It's nothing to do with the browser.
You just turn [b] text [/b] into <b> text </b> using regular expressions.

It is very simple to implement the basic BBCode tags yourself, like Marcus mentioned.
You could simply use str_replace to replace the BBCode tags with their HTML counterparts.
For example, for bold and italic text: -
$BBCodeTags = array("[b]", "[/b]", "[i]", "[/i]");
-
$HTMLTags = array("<strong>", "</strong>", "<em>", "</em>");
-
$out = str_replace($BBCodeTags, $HTMLTags, $in);
-
Other, more complex tags may require regular expressions, like the [url] tags: -
$regex = '#\[url\](.*?)\[\/url\]#is';
-
$replace = '<a target="_blank" href="$1">$1</a>';
-
$out = preg_replace($regex, $replace, $in);
-
You get the point.
If your not up to that, there is a PEAR class and probably some free PHP classes available.

That's fantastic guys. I was going to do it that way, but I didn't know you could use str_replace with arrays! Anyway, that will be much easier. I need to practice with regex though, as somethings I want to do could be complex. But you have given me lots to work on thanks!

Regexps are awful! But necessary.

Yea. Regex can be very annoying. Too bad they made them so damn useful :)
Happy coding! 8)

I am confused. looked at quite a few regex websites, but none are complete with knowledge. Do you guys have a recommended regex site with all the commands?
I have some questions about this:
Isn't the # indicating commenting?
What is the "is" on the end of line 2?
If I am asking the wrong questions, let me know a site and I will work it out because these more involved regex ones I have never spent any time on. Thanks again.

I have some questions about this:
Isn't the # indicating commenting?
What is the "is" on the end of line 2?
The # there marks the beginning and end of the regex itself.
The / char is typically used, but you can use other chars if you chose to do so. The # char is just a personal preference of mine.
The same regex could have been written like so and it would have made no difference. - /\[url\](.*?)\[\/url\]/is
The 'i' and 's' at the end are options.
The 'i' makes the search case-insensitive, while the 's' includes the new-line char in the dot-class, effectively making the search capable of spanning multiple lines.
Check out Regular-Expressions.inf o. Lots of useful info there.

Hi All,
I'd like enable visitors to my website to use bbcode and emoticons
whilst entering text into a form. Are there any standard lumps of
php/javascript I can use for this purpose?. In particular the
encoder/decoder for the emoticons & bbcode and any examples of form layouts
for textual input with all the appropriate '' and emoticon buttons?.
Ta in advance,

hi there,
i'm desperately looking for an HTML to BBCode (and vice versa) converter,
either as a COM component or vbScript for use in an ASP (not .NET)
web-application. i sure could write one on my own, but my vbscript/COM
skills are a little rusty since I work with C# and .Net for almost the last
decade.
does anyone know of something or has a snippet of code in his/her bottom
drawer? any hint/help is greatly appreciated.

Thanks!
