子文件夹url get参数在htaccess中不起作用

I have a website like www.abc.com/service/page.php?ids=social. I redirected site to www.abc.com/service/social. But i need to avoid this folder from url.Ex:www.abc.com/social.

Options +FollowSymLinks -MultiViews
 RewriteEngine on
 RewriteBase /service/
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule ^([a-zA-Z0-9]+|)/?$ page.php?ids=$1

Simply exclude "service" from the regex match:

RewriteRule ^service/([a-zA-Z0-9]+|)/?$ page.php?ids=$1

Place this code in site root .htaccess (i.e. parent directory of /service/):

RewriteEngine on
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule !^service/ service%{REQUEST_URI} [L,NC]
