I have a LAMP server with Ubuntu 9.10, Apache 2, Mysql 5 and PHP5. I want to disable PHP5 and use only PHP4. Can anyone explain how to do this?

I'm doing this because I need to simulate an environment similar to a legacy lamp server.

There are no PHP4 package in Ubuntu 9.10.

I guess you could download the PHP4 source from and compile it yourself.

Myself I would download the still supported Ubuntu 6.06, which does have PHP4 packages, and install it in a virtual machine. That way I could play around with old stuff without causing conflicts with my current system. You can find Ubuntu 6.06 iso files at

You could add the repos for an older version and install the PHP4 package, similar to what andol says.

How sure are you about that working in this case? (Myself I'm somewhat sceptic, considering the packages involved, the age of them, etc.) – andol Mar 7 '10 at 1:35
