@pyroDec 06.2003 — #Yes, if you need the regex engine to interpret a special character as a literal, you just escape it with a backslash. One thing I would recommend though - use [url=http://us3.php.net/manual/en/ref.pcre.php]PCRE[/url] instead of [url=http://us3.php.net/manual/en/ref.regex.php]POSIX[/url] regex. Perl compatible regex are much more powerful than POSIX extended.
