I am trying to install php5, the latest version of apache webserver and the latest version of mysql on a windows xp sp2 laptop. I also want to use Zend dev environment to write my php. I can install php4 and apache 1.3.3 with zend, and everything works fine. The problem is I'm trying to use functions for mysql that are only available for php5. I tried to upgrade to php5, and when I was using the installer for php, I installed to the php4 directory. When I call phpinfo(); it still shows as php version 4.x.x and I still can't call my functions. I have tried using all the tutorials for apache, mysql, and php, and I find them a bit confusing. I was wondering if anyone had some references to setting all this up for noobz like me

I don't work in windows much, but when I have to I've had good luck with WAMP a try, it was quick and easy for me.

You could also use vertrigoserve. If you simply Google it, it should be the first thing that pops up. It install mysql/php and apache
