The piece of code you have submitted (see under) is interesting,
although there is one thing I don't find meaning to, even after RTFM,
and STFG(Searching The Funky Google). In your regular expression
pattern '#<b>.*</b>#Uis', what does this do : #...#Uis
[snip]
$new_str = preg_replace_callback('#<b>.*</b>#Uis','myreplace',$str);
The # characters simply start and end the pattern. You can use any
character for that, really. I normally use /, but since it's present
in the pattern "</b>" and I didn't want to escape it, I used the #
character.
The characters after the pattern delimiters are called pattern
modifiers. They are explained here
(http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php),
but for the afraid-to-clicky-people:
U - ungreedy (makes sure the .* in the pattern doesn't match too much)
i - case-insensitive matching (in case you use <B> and </B>)
s - makes the dot character match newlines as well, otherwise text
between bold tags that included newlines wouldn't be matches.
