For those without the BBCode extension, here's a relatively elegant function to do the trick. 
Keep in mind that if you're using XHTML and one of your users tries to overlap lags <b>Like <i>so</b></i>, it will invalidate your markup. Still working on an expression for this. 

<?php 
   
function bb_parse($string) {
       
$tags 'b|i|size|color|center|quote|url|img';
        while (
preg_match_all('`\[('.$tags.')=?(.*?)\](.+?)\[/\1\]`'$string$matches)) foreach ($matches[0] as $key => $match) {
            list(
$tag$param$innertext) = array($matches[1][$key], $matches[2][$key], $matches[3][$key]); 
            switch (
$tag) { 
                case 
'b'$replacement "<strong>$innertext</strong>"; break; 
                case 
'i'$replacement "<em>$innertext</em>"; break; 
                case 
'size'$replacement "<span style=\"font-size: $param;\">$innertext</span>"; break; 
                case 
'color'$replacement "<span style=\"color: $param;\">$innertext</span>"; break; 
                case 
'center'$replacement "<div class=\"centered\">$innertext</div>"; break; 
                case 
'quote'$replacement "<blockquote>$innertext</blockquote>" $param"<cite>$param</cite>" ''; break; 
                case 
'url'$replacement '<a href="' . ($param$param $innertext) . "\">$innertext</a>"; break; 
                case 
'img'
                    list(
$width$height) = preg_split('`[Xx]`'$param); 
                   
$replacement "<img src=\"$innertext\" " . (is_numeric($width)? "width=\"$width\" " '') . (is_numeric($height)? "height=\"$height\" " '') . '/>'
                break; 
                case 
'video'
                   
$videourl parse_url($innertext); 
                   
parse_str($videourl['query'], $videoquery); 
                    if (
strpos($videourl['host'], 'youtube.com') !== FALSE$replacement '<embed src="http://www.youtube.com/v/' $videoquery['v'] . '" type="application/x-shockwave-flash" width="425" height="344"></embed>'
                    if (
strpos($videourl['host'], 'google.com') !== FALSE$replacement '<embed src="http://video.google.com/googleplayer.swf?docid=' $videoquery['docid'] . '" width="400" height="326" type="application/x-shockwave-flash"></embed>'
                break; 
            } 
           
$string str_replace($match$replacement$string); 
        } 
        return 
$string
    } 
?>

[EDIT BY danbrown AT php DOT net: Contains a bugfix provided by (ramonvandam AT gmail DOT com) on 04-SEP-09 to address an improperly-defined parameter.  Also contains a bugfix provided by (pompei2 AT gmail DOT com) on 15-FEB-10 to address improperly-closed tags.  Plus, contains another bugfix provided by (angad AT wootify DOT com) on 18-JUL-2011 to fix an issue where unsupported tags provided to the function could cause the script to time out.]

I strongly recommend checking out this code (pure php implementation of the c library) : 

If you can't install the pecl version, it avoids regexp and therefore is able to yield better results:
