The only difference between mod_cgi and mod_perl/mod_php is what level the CGI interface is decoded at. The browser itself sends the same data no matter what.

Under mod_cgi, the server guarentees certain environment variables and how the standard filehandles are setup. The server might modify the output headers slightly (though it definately won't under NPH).

Under mod_perl/mod_php, the server has already done much of the work of deparsing the browser's request, and may significantly alter the output before the response finally goes back. With mod_perl2, the potential for output-munging is even greater with the use of filters that are applied after the CGI or main handler has run.
