Say I have this:

PHP Code:

        $newstring = preg_replace($patterns, $replacements, $string); 


Now, $string may or may not have HTML tags in it, and if it does, the replacement will most likely b0rk them. So, how can I make it so that it just ignores anything between '<' and '>' and also '&' and ';'?

Also, how can I make it where it will ONLY affect things between '<' and '>' and also '&' and ';'? Thanks.
