Description:
------------
According to documentation http://php.net/manual/en/features.commandline.webserver.php

"URI requests are served from the current working directory where PHP was started, unless the -t option is used to specify an explicit document root. If a URI request does not specify a file, then either index.php or index.html in the given directory are returned. If neither file exists, the lookup for index.php and index.html will be continued in the parent directory and so on until one is found or the document root has been reached. If an index.php or index.html is found, it is returned and $_SERVER['PATH_INFO'] is set to the trailing part of the URI. Otherwise a 404 response code is returned."

So we can understand this as the apache rewirte equiv to

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]

But as soon as the URI contain a dot, this doesn't work.

Test script:
---------------
With a tree containif only a index.php

wget  -q http://localhost:8888/foo-1.1/bar
wget  -q http://localhost:8888/foo/bar.png
