url重写省略文件后缀

.htaccess
1.如果只是针对特定某一个文件

RewriteEngine On
RewriteRule something something.php [L]

http://example.com/something访问的文件为http://example.com/something.php

2.针对所有的php文件

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) $1.php [L]

3.其它方式^{(是否有效未做验证)}

路径/etc/apache2/apache2.conf

添加DefaultType application/x-httpd-php

如果想要解析为其他后缀

AddType application/x-httpd-php .ext
