I don't know hot to set up PHP and Apache because I had never done that.

But using some logic first you need to transfer packet from CD to your installation directory.

On Solaris that directory is /var/spool then install it using pkgadd command.

But don't take me serious and I will repeat one more: I don't work with apache and I never did , so I won't be responsible for any kind of damage.

Look at Apache documentation, PHP documenatation and think do you need to install PHP on more servers, zones and what is happing when you install that package.
