BBcode help? :)

Hey, I'm making a little news system and the last thing I need to do is include the BBCode. I read that I could use str_replace to do this? How would I set about doing it? :)

http://w3schools.com/php/func_string_str_replace.asp

If I was you, i'd just insert the original data into the database, then convert it when displaying it. I'm not sure if converting it then inputting would be quicker, I imagine so, but meh.

You would need to use preg_replace otherwise someone could do [b] and leave it open and the rest of the page would be in bold.

PHP Code:

---

$string = "[b]This[/b] text is in [b]bold[/b]";
preg_replace("/[b](.*?)[/b]/", "<b>$1</b>", $string);

That may not be 100% right but give it a go.

Yeah I was thinking that way but I just wanted to say include the file onto the index page so when say.. <b>Hiya</b> is displayed it automatically changes it to bold.

You can make a quick function like this:

Code:

---

function bbcode($content)
 {
 $content = preg_replace(”\[b\](.+?)\[\/b\]”, “<b>$1</b>”, $content);
 $content = preg_replace(”\[i\](.+?)\[\/i\]”, “<i>$1</i>”, $content);
 $content = preg_replace(”\[u\](.+?)\[\/u\]”, “<u>$1</u>”, $content);
 $content = preg_replace(”\[img\](.+?)\[\/img\]”, “<img src=\”$1\” alt=\”\” />”, $content);
 return($content);
 }

I get this when doing DUB's method.

 $content = preg_replace('/\[u\](.*?)\[\/u\]/is', '<u>$1</u>', $content);

Doesn't work when I apply the <strong></strong> tags.
