简化的htaccess

Question

我有一个.htaccess文件

RewriteEngine On
RewriteCond %{HTTP_HOST} ^localhost/host
RewriteRule (.*) http://localhost/host/$1 [R=301,L]

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?seg1=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?seg1=$1

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ index.php?seg1=$1&seg2=$2
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/$ index.php?seg1=$1&seg2=$2

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ index.php?seg1=$1&seg2=$2&seg3=$3
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/$ index.php?seg1=$1&seg2=$2&seg3=$3

我的问题，这些代码是否有简化的.htaccess？ 谢谢！

Answer 1

如果您的PHP可以正确处理空参数，那么为什么不

RewriteRule ^([-\w]+)?/?([-\w]+)?/?([-\w]+)?/?$ index.php?seg1=$1&seg2=$2&seg3=$3

而不是六条规则？

所以/ a会生成index.php？seg1 = a＆amp; seg2 =＆amp; seg3 =
