1 <?php # Transitional; supports both template APIs

8 # This file facilitates making a site with mixed PHP and html files. All URLs
9 # have the .html extension. One benefit of this is that you can change static
10 # html files to php scripts without having to update links.
12 # This script will pull the filename from the URL. It looks for a file with
13 # that name, and for one with the same basename, but with the .php extension
14 # and acts accordingly:
16 #--------------------------------------------#
17 # | .php file exists | no .php file #
18 #--------+--------------------+--------------#
19 # .html | load html file as | pass html #
20 # file | a template and run | file through #
21 # exists | run the php file | as is #
22 #--------+--------------------+--------------#
24 # .html | run php file | display 404 #
26 #--------------------------------------------#
30 # To activate this script in a directory, you'll need to:
32 # 1) make a symbolic link to (or copy of) this file in your directory. and
34 # 3) Set your webserver to run this script instead of html files. Here's how to
35 # do that with apache: put something like the following in you your .htaccess
36 # file (where /foo/ is the part of the url between the hostname and the
37 # filename.) The example below would work for this url:
38 # http://example.com/foo/bar.html
41 # RewriteRule ^$ /foo/run.php
42 # RewriteRule ^foo/[^/]*\.html$ /foo/run.php
