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.
