如何重写：
http://localmachine/product.php?c=water&p=Evian
进入：
http://localmachine/water/evian
如果我加上
RewriteRule ^([A-Za-z0-9_?-]+)/([A-Za-z0-9_?-]+)(/)?$ product.php?c=$1&p=$2 [NC,L]
我想在这一行发生冲突
RewriteRule ^(index\.php)/([^-]+)-([^/]+)(/.*)?$ /$1$4?$2=$3 [L,QSA]
这是我的htaccess：
RewriteEngine On
Options -Indexes
Options +FollowSymLinks
<Files .htaccess>
deny from all
</Files>
