More than 2 Instances of PHP on same Server?
Hi, I've got my own webserver and I have different sites on it. I normally set these up using Plesk , useing Plesk to add PHP to each site if the site needs it. I only have the option of using PHP 5.x.x. A new site uses software which requires PHP 4.x.x. Can I FTP and install PHP 4.x.x specifically for that site only?
Thing is I dont understand how this work, I mean is there ONE SINGLE instance of PHP for my Whole server, and when I add PHP to a iste Im simply saying , OK , you have access to PHP OR is there a seperate instance for each site. If the second case is true, obviously that would mean each site had its own php.ini file. And of course if the fisrt is true, then there is only one instance of the php.ini file.
If the first case is true, what I can do about the required lower instance of PHP for the new site?
If the second case is true, which directory shoudl I install PHP 4.x.x?
Thanks in advance
