Suppose you would like your PHP pages to masquerade as .html files. How would you accomplish that?
If you are running PHP on the Apache web server platform, you can take advantage of issuing server directives from an .htaccess file in the root web folder or in any sub folder.
Include in you .htaccess file:
AddType application/x-httpd-php .html
If you are running PHP through a ‘script wrapper’ the code would look something like this:
Action application/x-myhost-sphp4 /cgi-bin/php-cgiwrap/myaccountname/php4.cgi AddType application/x-myhost-sphp4 .php .html
You need to consult your individual hosting provider for details on how to invoke the wrapper, if any.
