It depends on whether you are doing a compile from source install or with rpms.  If you are going to compile from source, you may want to save the configure parameters that you used with 4.0.4pl1.  To do this, put <? phpinfo(); ?> in a script and run it through your web browser.  You will the configuration parameters at the top.

Hi--

I'm currently running 4.0.4pl1 on RedHat 7.0 and I want to upgrade to PHP 4.2.2....is there anything special I have to do BEFORE or AFTER the install?  Or is it just a straight re-install of PHP on top of the current Version?  THANKS!
