22 # This file facilitates making a site with mixed PHP and html files. All URLs
23 # have the .html extension. One benefit of this is that you can change static
24 # html files to php scripts without having to update links.
26 # This script will pull the filename from the URL. It looks for a file with
27 # that name, and for one with the same basename, but with the .php extension
28 # and acts accordingly:
30 #--------------------------------------------#
31 # | .php file exists | no .php file #
32 #--------+--------------------+--------------#
33 # .html | load html file as | pass html #
34 # file | a template and run | file through #
35 # exists | run the php file | as is #
36 #--------+--------------------+--------------#
38 # .html | run php file | display 404 #
40 #--------------------------------------------#
44 # To activate this script in a directory, you'll need to:
46 # 1) make a symbolic link to (or copy of) this file in your directory. and
48 # 3) Set your webserver to run this script instead of html files. Here's how to
49 # do that with apache: put something like the following in you your .htaccess
50 # file (where /foo/ is the part of the url between the hostname and the
51 # filename.) The example below would work for this url:
52 # http://example.com/foo/bar.html
55 # RewriteRule ^$ /foo/run.php
56 # RewriteRule ^foo/[^/]*\.html$ /foo/run.php
