For example:
http://www.example.com/contact
http://www.example.com/contact.php
Not only does the first URL look cleaner, but if I decided to switch languages, it would be less of an issue.
So how does one implement this? Here is the .htaccess code I found works best:
不仅第一的网址看起来更简洁，但如果我决定切换语言，这将不再是一个问题。
那么，如何实现呢？下面是我发现最好。htaccess代码：
# If requested URL-path plus ".php" exists as a file
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
# Rewrite to append ".php" to extensionless URL-path
RewriteRule ^(([^/]+/)*[^.]+)$ /$1.php [L]
