Another primary difference is that .rvt files start out with the expectation that they are outputting literal HTML content until the escapement <? ?> sequence is encountered. Think of it as rvt files being "HTML files with embedded blocks of Tcl", while .tcl files are just pure Tcl script starting out in Tcl interpretation mode. I don't think it is wise to change the meanings of .rvt/.tcl to have non-standard interpretations, since it may complicate maintenance and sharing of your code with others in the future.
PHP was initially developed as a HTML language and so when pages are run they are always assumed to be HTML content until the escapement <? ?> sequence is encountered. When you require/include other PHP files within a PHP page, the extension actually doesn't matter (some people use .inc extensions for such included files). Those included files are assumed to be raw PHP-code and do not require an additional escapement sequence since it was being included from such a block.
