mod_rewrite, SCRIPT_NAME, and PATH_INFO

Argh, why isn't PATH_INFO set when using mod_rewrite? I have the following lines in my .htaccess file to make PHP pages be able to be served without the .php:

RewriteCond %{REQUEST_FILENAME}.php -f

RewriteRule . %{REQUEST_FILENAME}.php [L]

If my page is /foo.php and I visit it as /foo/bar, I expect SCRIPT_NAME to be /foo and PATH_INFO to be /bar. PATH_INFO isn't set, but if I visit the page as foo.php/bar it is. Also, SCRIPT_NAME points to the actual file location. So, if I visit the page as /foo/bar, SCRIPT_NAME is set to /foo.php and not /foo.

The net result of all this is that there's no way to split out the actual script name you requested from the PATH_INFO.

My only alternatives are using MultiViews, which does work as expected (though MultiViews has gotta be overkill just for this), and hard-coding the base path to the script in the script. And, even though the mod_rewrite documentation says the variables SCRIPT_URL and SCRIPT_URI should be set, they aren't.

Did you try:

RewriteRule . %{REQUEST_FILENAME}.php%{PATH_INFO} [L]

Weird. No, but I'll give it a shot.

Whoa, that worked. Why did that work?

Now all I have to do is figure out how to set the SCRIPT_NAME to the right thing and I'm golden. Got any ideas about that?

Thanks for your help.

P.S. I realize that as long as I have the REQUEST_URI and the PATH_INFO I can derive the SCRIPT_NAME. I'm just wondering if there's any similar trick I can do in mod_rewrite with environment variables or something.

Ah, I get why that worked now. Makes sense. Thanks again.
