Answer 1

$replaced = preg_replace('#<a href="forum.php\?id=(\d+)">([^<]+)</a>#i','<a href="f-$1-$2.html">$2</a>', $template); 

Answer 2

Your regex has a couple of issues. First, the delimiters don't match. You open with # but close with @; this won't work. Stick with one. You also aren't escaping other characters in the string. Use this and it should work:

#<a href="forum\.php\?id=(.*?)">(.+?)</a>#
