You may have already realized it. Planet PHP has now search functionality. It searches through all the entries we have in our archive with
MySQLs fulltext capability. Maybe useful for some of you, if you remember having read something on a PHP related blog, but you can't remember where exactly that was. And it works for RSS, too.
http://www.planet-php.net/rdf/search/chregu would give you an RSS 1.0 feed of all entries, which contain my nickname ;)
