whether it is possible to install and configure php without using sudo apt-get install php5 ???

You can install a php enabled server for a high port under your id entirely.

Tomcat is a jsp/jdbc thing, but some run php there, too. It seems odd to mix! How to run PHP applications in Tomcat 7 with PHP-Java bridge?
