You actually don't even have to run a second instance of Apache. From what I've heard of other hosting companies doing, you can use the same Apache installation and run PHP4 and PHP5 concurrently.

However, the only thing you'd have to do is one of the following:

1) For PHP4 apps and scripts, leave the .php extension and rename all PHP5 apps and scripts with a .php5 extension. Where you have the string:

DirectoryIndex index.php index.html

add: index.php5 to it. And where you have the string:

AddType application/x-httpd-php .php

Change it to:

AddType application/x-httpd-php4 .php

Also, add another line:

AddType application/x-httpd-php5 .php5

Make sure you include both the php4 and php5 modules, restart apache and voila! PHP4 and PHP5 on the same server using 1 installation of Apache.

2) Do the same as above, but use .php4 extensions instead of .php5.

3) Additionally, after doing 5 minutes of Googling, I found that you can have .htaccess files to control which applications use PHP4 and which use PHP5 with the following directive:

AddHandler application/x-httpd-php5 .php

This would circumvent having to rename the extensions of your PHP files, as you could then do directory specific PHP4/5 app running. You still have to make certain Apache has both the PHP4 and PHP5 modules loaded, obviously.
