这应该有效：

RewriteEngine On
RewriteRule \/([^\/]+)\/$ $1.php

它将为您提供以url的最后一段命名的文件：

It will serve you the file named after the last segment of the url:

http://example.com/shops/shopname1/ -> shopname1.php

http://example.com/shops/shopname1/ -> shopname1.php

http://example.com/shops/ -> shop.php

http://example.com/shops/ -> shops.php
