Hiding PHP as another language

In general, security by obscurity is one of the weakest forms of security.
But in some cases, every little bit of extra security is desirable.

A few simple techniques can help to hide PHP, possibly slowing
down an attacker who is attempting to discover weaknesses in your
system. By setting expose_php = off in your php.ini file, you
reduce the amount of information available to them.

Another tactic is to configure web servers such as apache to
parse different filetypes through PHP, either with an .htaccess

directive, or in the apache configuration file itself. You can
then use misleading file extensions:
