php website issue

Hi, I've been keeping a local mirror of the php website for a few years now, has always worked well. Recently though I've noticed the following: When I do search in the Function List for e.g. "base64", I am presented with a list of hits, presumably ordered by quality. The problem is - those hits link to pages on "php.net", not on my local site. The same behaviour is also evident on official php mirrors - go to ch.php.net and do the search for base64. The list of hits has links to php.net, not ch.php.net. thanks Per Jessen
