如何让 ip 在我的 htaccess 中与允许/拒绝一起使用（使用 php）

Question

How do I get the IP, with PHP, that I have to use for my htaccess to allow specific domains access to my content?

I used gethostbyname($_SERVER['HTTP_HOST']) to get the ip, but that seems not to be the right one? Or maybe something is wrong with my .htaccess file?

Order deny,allow
Deny from All
Allow from 77.111.240.115

I now see that there are a lot websites hosted on this IP, is there a way to get this working?

Answer 1

You did mentioned that you are looking to just allow specific domains to access your website.

Try this in your .htaccess and it won't require you to deal with IPs etc.

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} 
!^http(s)?://(www\.)?yoursite.com [NC]
RewriteCond %{HTTP_REFERER} 
!^http(s)?://(www\.)?othersite.com [NC]
RewriteRule \.(jpg|jpeg|png|gif|html|php)$ - [F]

The above thing will allow access to your own website and that other website to files like jpg gif html etc.

If you want you can add other file extensions in it and if you want you can add other websites in it.
