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) {
while (preg_match_all('
\[(.+?)=?(.*?)\](.+?)\[/\1\]', $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</a>"; break;
case 'color': $replacement = "<span style=\"color:
$param;\">$innertext</a>"; 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':
$v4ideourl = parse_url($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, $content);

return $string;
