note 93349 added to function.bbcode-create

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': $videourl = parse_url($innertext); parse_str($videourl['query'], $videoquery); if (strpos($videourl['host'], 'youtube.com') !== FALSE) $replacement = '<embed src="http://www.youtube.com/v/' . $videoquery['v'] .
