[SOLVED] Converting [b] to html

[smerny]

What is the best way to convert [ b][ i] etc to html?

 

I would like it ONLY to convert if there is a matching end tag, so as not to have the rest of the page also edited...

 

so... "[ b]blahblah[ /b] [ b]blah" would be converted to "<b>blahblah</b> [ b]blah"

You could use str_replace:

str_replace("[b]", "<b>", $string);

 

Hmm, after reading the end of your post, this wouldn't be waht you're looking for. Just disregard it.

Your best bet is regex if you want the tags to match.

 

$str = '[i]Hello [b]World[/b][/i] [u]Underline[/u]';

$str = preg_replace('~\[b\](.*)\[/b\]~', '<b>$1</b>', $str);
$str = preg_replace('~\[i\](.*)\[/i\]~', '<i>$1</i>', $str);
$str = preg_replace('~\[u\](.*)\[/u\]~', '<u>$1</u>', $str);

I'd use a non-greedy match:

 

(.*?)

i really need to learn this preg stuff... anyone suggest a good tutorial?

You need to learn regular expressions; specifically Perl compatible regular expressions if you want to use them with the 'preg' functions. There's a 'resources' sticky in the regex forum.
