Domain name in URL as variable

问题

My .htaccess file has the following code:

RewriteEngine on
RewriteRule ^/?(.*)$ index.php?domain=$1 [L]

I'm trying to get domain names as variables from URLs like:

hxxp://www.example.com/www.domain.name or

hxxp://www.example.com/subdomain.domain.name or

hxxp://www.example.com/domain.name

but with $_GET['domain'] my variable is always 'index.php' and not the domain names.

With hxxp://www.example.com/domain/www.domain.name and .htaccess code

RewriteEngine on
RewriteRule ^domain/?(.*)$ index.php?url=$1 [L]

everything is OK, but I would like to remove the 'domain/' part from the URLs.

I've searched for this, but couldn't find anything. Could someone please help me with this?

回答1:

something like

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?domain=$1 [L]

in this case $1 will be:

http://site/www.example.com        $1 = www.example.com
http://site/www.example.com/xyz    $1 = www.example.com/xyz

Try this rule:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^[^/.](\.[^/]+)+$ index.php?domain=$0 [L]

This will rewrite any request with a URL path that contains at least one dot (foo.bar, foo.bar.baz, etc.) to your index.php.
