PHP5 on Windows with Apache 1.3.29

Hey everyone, I am just starting a fairly big web project and I decided to use PHP because it has become de-facto on most web hosting companies and PHP 5 has some strong OO features which I like... Anyways, I started by downloading Zend Studio Client+Server which mentions that you can select if you want to use PHP4 bundled or an existing installation of PHP. However, when installing I never got such an option so I could pinpoint to my php5 directory. Then I tried to go manually about it and installed apache 1.3.29. Then I loaded php5_module and so on. It seems to run with the default modules loaded but as soon as I add any of them stuff from pecl-5.0.0b4-Win32.zip I get a crash.. Ideally, I would like to setup Zend Studio Client/Server with PHP5 and MySQL but I can't seem to find documentation for any of this. Any suggestions? Thanks in advance. George Diamantopoulos
