Re: [PHP] Re: BBCode?
Thanks a lot, but do you know how to do the same with ereg_replace? I'm
trying to learn PCRE, but until I do, I won't be able to add anything to
this...
?php
function bbcode($text){
$text = ereg_replace((\\[i\\])([^\\[]+)(\\[/i\\]),'i\\2/i',$text);
return $text;
}
print bbcode('[i]This[/i] is a [i]test[/i].');
?
Works...

Re: [PHP] Re: BBCode?
Thanks, but that doesn't allow nested tags (a [b] tag inside of an [i]
tag, for example).

If you want to deal with nested tags then it's probably best to replace each opening and closing tag individually. Otherwise you might end up with some fiendishly complicated regex. Did I say I preferred the PCRE functions to the EREG ones? Well using preg_replace() you can put all your search strings in one array and all the corresponding replacement strings in another and it'll replace all those tags for you in a single operation: $text = '[i]This[/i] is a [i]test[/i].'; $search_for_tags = array(/\[i\]/, /\[\/i\]/); $replace_with_tags = array(i, /i); $text = preg_replace($search_for_tags, $replace_with_tags, $text); print $text; -- Jason Wong - Gremlins Associates - www.gremlins.biz Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* Ignorance must certainly be bliss or there wouldn't be so many people so resolutely pursuing it. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: BBCode?
This will replace all versions (open and close) of bold, italicize and underline tags with brackets using preg_replace. $text = preg_replace(/\[(\/)?([biu])\]/,\\1\\2,$text) ; definition - find [ = \[ - match IF slash exists = (\/)? - match one of the following = ([biu]) - find ] = \] - matches get put into 'memory' (\\1 \\2) even if not found (ie. slash didn't exist). - replace with 'first match' 'second match' - NOTE : in PCRE regexs, brackets and forward-slashes are special characters and must be escaped (preceded with a back-slash) when looking for them as regular characters. /definition Even if you do not know PCRE yet, don't hamstring yourself looking for a solution that is too complicated and time-consuming. EREG does not work very well on this type of problem. Buck up, learn PCRE and use this type of solution (if you find something that works for you, use it...by no means does the code above cover every tag you 'may' want to use). Builder.com has a pretty good regular expression checker for PERL-style regexs that make PCRE pretty easy. http://builder.com - Go To: Web Scripting (left menu) - Cool Tools (right menu) - Regular Expression Inspector (2/3 way down page) .mike === Michael Geier CDM Sports, Inc.

Thanks, but that doesn't allow nested tags (a [b] tag inside of an [i] tag, for example). Nested tags? Do you mean [ib] ? Or [i[b]]? If you mean [ib], then I'm afraid what you want cannot be done in ereg_replace.

Try this:

$open=\\[;
$close=\\];
$pattern=$open.(.).$close.([^.$open.]+).$open./.(.).$close;
$temp = $text;
$text = ereg_replace($pattern,'\1\2/\3',$text);
while($temp != $text)
{
$temp = $text;
$text = ereg_replace($pattern,'\1\2/\3',$text);
}
return $text;
}
print format_text('[i] this is a [b]bold[/b] test [/i]');

I would have thought nested tags would have meant: [i]something something [b]bolder[/b] something[/i], since ib and ib aren't valid HTML, can't see why they'd have been adopted by BBcode.

Re: [PHP] Re: BBCode?
Thanks, but that isn't what I want. The point behind BBCode is allowing
a small, simpler, securer, subset of HTML. I.e.
[img=http://domain.com/image.gif] changes to img
src=http://domain.com/image.gif; alt= /

It's not working because it's doing a greedy match. Try (I prefer the PCRE
functions over EREG):
$text = preg_replace(/\[i\](.*)\[\/i\]/U, i$1/i, $text);
?
function bbcode($text)
{
$text = str_replace([,,$text);
$text = str_replace(],,$text);
return $text;
}
print bbcode([i]This[/i] is a [i]test[/i].);
?
This code is simply not suitable. The object is to replace tags as an entity
as opposed to simply replacing '[' with ''.
