Suppose i have one website with simple pages in php like
page1.php
page2.php
Now there is one page where i want some detailed functioning and i want to use python for that and it will look like
page3.py
and in other page i want to use java like
page4.jsp
Provided i have installed python , java on webserver.
Is it possible?
Yes. It’s possible. Where you will find yourself in trouble is when you want to share server-side information among them (I.E. sessions).
Other than that, you can use (but I would advise against it) all languages you want on a website.
