Tricking Microsoft Script Editor to edit PHP files

Microsoft Script Editor is a great tool to edit HTML pages and debug client javascripts. However, it only recognize file with several extensions, and show unformatted pages to .php and .tpl files. It seems that Microsoft does not want you to use this tool to edit PHP and template files. Many people want this feature and have to change the file extension back and forth. Needlessly to say, this is a tedious work and prone to errors.
Today I found that you can hardlink a file under Windows XP, just like the command "ln" on UNIX. A hard linked file looks like a regular file, but points to another file. If you change the contents of one file, the another changes as well. Let's say that we need to edit file index.php, we can create a hardlink file called index.html. Now every changes made to index.html go into index.php. In this way we can edit file contents in Frontpage or Script Editor, but test it with index.php.

The command to create a hardlink file is
fsutil hardlink create index.html index.php

Note that the new file name is before the old file name.
