BB code

where is a good place to begin to look at how to create a bulletin board?  i am looking at building my own using php and want to know where to get started with this.

When doing myself I used my own regex style functions, then found these built in routines, but still not got back to trying them out...

If you'd tested this function, you'd found out that you forgot to escape every single square bracket. It's an easy fix though. I also think you'll need to use the lazy (.*?) instead of (.*), to make it function with nested tags. I've used this before:

 

<?php
function bb2html($text) {
$find = array(
	'~\[b\](.*?)\[/b\]~s',
	'~\[i\](.*?)\[/i\]~s',
	'~\[u\](.*?)\[/u\]~s',
	'~\[size=(.*?)\](.*?)\[/size\]~s',
	'~\[color=(.*?)\](.*?)\[/color\]~s',
	'~\[highlight=(.*?)\](.*?)\[/highlight\]~s',
	'~\[code\](.*?)\[/code\]~s'
);
$replace = array(
	'<strong>$1</strong>',
	'<em>$1</em>',
	'<span style="text-decoration: underline;">$1</span>',
	'<span style="font-size: $1em;">$2</span>',
	'<span style="color: $1;">$2</span>',
	'<span style="background-color: $1;">$2</span>',
	'<pre>$1</pre>'
);
return preg_replace($find, $replace, $text);
}
?>

OK, I fixed them, and even with out escaping the brackets, they still worked...

Here's part of mine...

$base = "http://www.a.b.com/icon/";
$pattern = array(
				'/\[b\](.+?)\[\/b\]/is',
				'/\[i\](.+?)\[\/i\]/is',
				'/\[u\](.+?)\[\/u\]/is',
				'/\[h1\](.+?)\[\/h1\]/is',
				'/\[h2\](.+?)\[\/h2\]/is',
				'/\[h3\](.+?)\[\/h3\]/is',
				'/\[h4\](.+?)\[\/h4\]/is',
				'/\[sub\](.+?)\[\/sub\]/is',
				'/\[sup\](.+?)\[\/sup\]/is',
				'/\[tt\](.+?)\[\/tt\]/is',
				'/\[s\](.+?)\[\/s\]/is',					
				'/\[em\](.+?)\[\/em\]/is',
				'/\[strong\](.+?)\[\/strong\]/is',
				'/\[samp\](.+?)\[\/samp\]/is',
				'/\[kbd\](.+?)\[\/kbd\]/is',
				'/\[code\](.+?)\[\/code\]/is',
				'/\[code=(.+?)\]

thanks for the replies there is some good stuff on them.  If you can think of any others that would be great i want to know all i can before i start to build.
