bpcode error checking

[chrispadfield]

How about some basic error checking for bpcode. Ie for every open tag there must be a closed one. If there is not then instead of posting the page goes to a preview page with the post there ready for editing.

This idea is adapted from the "force preview" thread.

I've created regexes that only will be parsed when they are closed...The only problem is that they require php > 3.09

$bbcode=preg_replace("/(\[url=)(.*)(])(.*)(\[\/url\])/siU", "<a href=\"\\2\" target=_blank>\\4</a>",$bbcode);

or

$bbcode=preg_replace("/(\[url])(.*)(\[\/url\])/siU", "<a href=\"\\2\">\\2</a>",$bbcode);

etc...

Works flawlessly with every possible combination of multiple bbcodes (nested, multiple etc..)
