.htaccess重写URL同一页面

Question

我想重写以下网址：

localhost/beta/coupons.php?cat=promotions point to ---> localhost/beta/coupons/promotions


localhost/beta/coupons.php?city=ny point to ---> localhost/beta/coupons/ny

我在.htaccess

中运行此代码

    <IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase  /beta/


RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^coupons/([^/]*)$ coupons.php?cat=$1 [L]

RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^coupons/([^/]*)$ coupons.php?city=$1 [L]


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^coupons/([^/]+)/([^/]+)?$ coupons.php?cat=$1&city=$2 [L]

</IfModule>

代码只运行第一次重写，第二次不起作用。

非常感谢你的时间。
