Do .php files without any PHP in them get passed to the interpreter?

On a standard LAMP stack, do .php files without any PHP in them get passed to the PHP interpreter?

In other words, is there a performance/processing loss for creating a .php file without actually including any PHP in it, versus just making it a .html file?

Yup - after all, no other component except for the PHP parser is fit to decide whether the file contains PHP!

Potentially, yes, although it will be minimal in most cases unless you have really, really loads of traffic.

I agree that the performance loss for processing a php file without php-content probably is minimal, but what cache-headers does it set? The whole idea with php is to create dynamic pages, so I don't expect to find a cache-header far into the future on php files (unless it is specifically set inside the php file). Therefore I assume that a php file without any php-statements will be fetched every time and not cached.

@some that will depend on the server's default settings for the file type... But it's indeed a good point. It's advisable to look for what headers are sent
