different PHP configs for multiple sites on same machine

Hi all. Is it possible to have different php.ini settings for different
sites running on the same server (Apache)?



What I want to do exactly is change the include_path on a per-site
basis, without having to call ini_set in each page.



I have the following:



/home/vservers/cms.mysite.com

/home/vservers/wwwdev.mysite.com

/home/vservers/cmsdev.mysite.com



And I would like to be able to run an individual php.ini file for each.



I'm pretty new to administering Apache so I'm just wondering if this Is
doable?



Cheers,
Pablo
