All you need to do is to put arp into diferrent group.

Default:

<pre><code>-rwxr-xr-x 1 root root 48K 2008-11-11 18:11 /usr/sbin/arp*
</code></pre>

With command:

<pre><code>sudo chown root:www-data /usr/sbin/arp
</code></pre>

you will get:

<pre><code>-rwxr-xr-x 1 root www-data 48K 2008-11-11 18:11 /usr/sbin/arp*
</code></pre>

And because apache is a daemon running under the user www-data, it's now able to execute this command.

So if you now use a PHP script, e.g.:

<pre><code>&lt;?php
$mac = system('arp -an');
echo $mac;
?&gt;
</code></pre>

you will get the output of linux <code>arp -an</code> command.

too late to answer but here is my approach since no one mentioned this here: 
why not a client side solution ? 
a javascript implementation to store the mac in a cookie (you can encrypt it before that) 
then each request must include that cookie name, else it will be rejected. 
to make this even more fun you can make a server side verification 
from the mac address you get the manifacturer (there are plenty of free APIs for this) 
then compare it with the user_agent value to see if there was some sort of manipulation: 
a mac address of HP + a user agent of Safari = reject request.

blocks|key|1239302|text|在使用iptables的linux下，您可以使用mac地址和ip将每个对web服务器的请求记录到一个文件中。从php查找最后一项与ip地址和获取mac地址。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1239303|如上所述，请记住mac地址来自跟踪中的最后一个路由器。|1239304|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

blocks|key|1454452|text|也许获取Mac地址并不是在互联网上验证客户端机器的最佳方法。请考虑改用令牌，该令牌由管理员登录存储在客户端浏览器中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1454453|因此，只有当管理员通过其浏览器将该令牌授予客户端时，客户端才能拥有该令牌。如果令牌不存在或无效，则客户端的计算机无效。|1454454|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Perhaps getting the Mac address is not the best approach for verifying a client's machine over the internet. Consider using a token instead which is stored in the client's browser by an administrator's login. 

Therefore the client can only have this token if the administrator grants it to them through their browser. If the token is not present or valid then the client's machine is invalid.

blocks|key|1239372|text|您可以使用openWRT轻松完成此操作。如果你使用强制门户，你可以混合使用php和openWRT，并在IP和mac之间建立一个关系。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1239373|您可以使用以下命令编写一个简单的PHP代码：|1239374|+$localIP+=+getHostByName(getHostName());+|code-block|syntax|javascript|1239375|稍后，您可以使用openWRT转到/tmp/dhcp.leases，您将获得表单中的内容：|offset|length|style|CODE|1239376|+e4:a7:a0:29:xx:xx+10.239.3.XXX+DESKTOP-XXX+|1239377|现在，您有了mac、IP地址和主机名。|1239378|entityMap^0|0|0|0|H|G|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|X|8|@$K|Y|L|Z|M|N]]|9|@]|A|$]]|$1|O|3|P|5|F|7|10|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

You can do this easily using openWRT. If yo use a captive portal you can mix php and openWRT and make a relation between the IP and the mac.

You can write a simple PHP code using:

<pre><code> $localIP = getHostByName(getHostName()); 
</code></pre>

Later, using openWRT you can go to <code>/tmp/dhcp.leases</code>, you will get something with the form:

<pre><code> e4:a7:a0:29:xx:xx 10.239.3.XXX DESKTOP-XXX 
</code></pre>

There, you have the mac, the IP address and the hostname.

I need to know the MAC and the IP address of the connect clients, how can I do this in PHP?
