Can php select which ini file to use?

Hi all, I've been playing around installing PHP5 (b3) tonight. I managed to get it running on my Windows XP Pro box as a Module, bar one thing. I have Zend Studio 3 installed which uses the Debugger and Profiler which adds a whole host of extra stuff to the php.ini file in the Windows directory. My question is this - is there any way to get PHP to use a different ini file? I need PHP4 and 5 on the same machine and have two Apache conf files and two short-cuts to start the one I need. PHP4 works perfectly and PHP5 works but I have to click through a whole bunch of warning dialogs first because of all the Zend extensions it's trying (but failing) to load. -- Best regards, Richard mailto:rich@launchcode.co.uk
