First, you need to enable named pipes with enable-named-pipe in the [mysqld] section of my.ini. Then, just don't use 'localhost' (which uses TCP/IP on Windows) as the hostname in mysql_connect(). :-) Using '.' (just a period) specifies named pipes. But by using a blank/empty string for hostname, named pipes will be used if available, else TCP/IP. Note that 'localhost' on *nix is special and doesn't use TCP/IP, but the faster Unix sockets. But again, by just leaving the hostname blank, this will be used anyway. So I just leave the hostname blank when MySQL is on the local system to get the best connection available. It seems that an address is only needed to connect to a separate MySQL box. See also the first 2 paragraphs here in the manual: http://www.mysql.com/doc/en/Can_not_connect_to_server.html Hope that helps.
