pecl4win 
I don’t normally work with pecl much but on a forum I use I noticed a thread on pecl and windows. When I went to the pecl site, all I could find was the *nix information and packages - nothing for M$ - and thought that was odd since PHP has such awesome documentation. Do a little investigating and find pecl4win.php.net
Wonder why there isn’t a simple link between the main pecl site and the pecl4win site…
