I think you can. At one point I had my computer set up with IIS for testing php pages with php4. When php5 was released, I installed it without uninstalling php4. I vaguely remember associating the .php4 and .php5 extensions with their respective versions of php in IIS, but it was a while ago and I didn't really know what I was doing . I also don't remember if I had to do anything else to get it to work. I've reformatted since then and haven't set IIS up again, so I can't check... I'd definatley recommend trying it on another computer before doing it on a server.

Might cause an error when you attempt to run both at the same time..

you can run both, but only one can be associated with the extention .php (or any other extension)


for pages you write your can specify .php4 or .phh5 for the one not associated with the "default" version of php.

Some resources for you:

http://www.phpit.net/blog/running-php4-and-php5-together/

Works fine on my server. So long as you assign extensions.

thanks all.


ended up fiding a server more instead got tired of renaming php files
