How can I prevent a page from loading if there is no javascript, but using
php instead of ?

I have a page with php and other stuff in the code. What I need to do is a
way to check with php if there is javascript enabled in the browser. This
way, the whole page source will be prevented to be loaded, instead of
using that only prevents the page from loading, but allows the source
code.
