php.ini for each virtual host

[tumtum]

I am having an issue with a new clients request. They sent over a mostly completed website along with the database setup and everything, I untarred and things worked fine except:
They are using Ying Zhang's mysql session handler code. The server they are running on here is running virtual hosts and I cannot make the changes to php.ini that are required for this mysql libray.

Do I tell the client they are out-of-luck and have to re-write (using regular session code) or is there a way I can run multiple php.ini files and assign each one to a virtual host?????

I don't know about a second php.ini (I'm sure it's in documentation though), however one solution is that you could alter the ini settings in the scope of the script that is running.
see [man]ini_alter[/man] many websites call code to set everything up before the code for the page executes. you could call this code before every page.
