This is an old post, but get it with this:

<pre><code>function getLocalIp()
{ return gethostbyname(trim(`hostname`)); }
</code></pre>

For example:

<pre><code>die( getLocalIp() );
</code></pre>

Found it on another site, do not remove the trim command because otherwise you will get the computers name.

BACKTICKS (The special quotes):
It works because PHP will attempt to run whatever it's between those "special quotes" (backticks) as a shell command and returns the resulting output.

<pre><code>gethostbyname(trim(`hostname`));
</code></pre>

Is very similar (but much more efficient) than doing:

<pre><code>$exec = exec("hostname"); //the "hostname" is a valid command in both windows and linux
$hostname = trim($exec); //remove any spaces before and after
$ip = gethostbyname($hostname); //resolves the hostname using local hosts resolver or DNS
</code></pre>

blocks|key|989500|text|获取本地计算机的外部IP地址的可靠方法是查询路由表，尽管我们在PHP中没有直接的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|989501|但是，我们可以通过将UDP套接字绑定到公共地址并获取其地址来让系统为我们做这件事：|989502|$sock+=+socket_create(AF_INET,+SOCK_DGRAM,+SOL_UDP);
socket_connect($sock,+"8.8.8.8",+53);

A reliable way to get the external IP address of the local machine would be to query the routing table, although we have no direct way to do it in PHP.
However we can get the system to do it for us by binding a UDP socket to a public address, and getting its address:
<pre><code>$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_connect($sock, &quot;8.8.8.8&quot;, 53);
socket_getsockname($sock, $name); // $name passed by reference

// This is the local machine's external IP address
$localAddr = $name;
</code></pre>
<code>socket_connect</code> will not cause any network traffic because it's an UDP socket.

blocks|key|988950|text|取决于您所说的本地：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|988951|如果您所说的本地是指执行PHP代码的服务器/系统的地址，那么仍然有两种方法可以讨论。如果PHP是通过web服务器运行的，那么您可以通过读取$_SERVER['SERVER_ADDR']来获取服务器地址。如果PHP是通过命令行界面运行的，那么您可能必须通过shell执行ipconfig+(Windows)+/+ifconfig+(*nix)并grep出地址。|offset|length|style|CODE|988952|如果你说的本地地址是网站访问者的远程地址，而不是他们的外部IP地址(因为你特别提到了192.*)，那么你就不走运了。NAT路由的全部目的是隐藏该地址。您无法识别IP地址后面的单个计算机的本地地址，但有一些技巧(用户代理，可能是mac地址)可以帮助区分是否有多台计算机从同一IP访问。|988953|entityMap^0|0|1X|N|3Q|8|4B|8|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|K|$]]

Depends what you mean by local:

If by local you mean the address of the server/system executing the PHP code, then there are still two avenues to discuss. If PHP is being run through a web server, then you can get the server address by reading <code>$_SERVER['SERVER_ADDR']</code>. If PHP is being run through a command line interface, then you would likely have to shell-execute <code>ipconfig</code> (Windows) / <code>ifconfig</code> (*nix) and grep out the address.

If by local you mean the remote address of the website visitor, but not their external IP address (since you specifically said 192.*), then you are out of luck. The whole point of NAT routing is to hide that address. You cannot identify the local addresses of individual computers behind an IP address, but there are some tricks (user agent, possibly mac address) that can help differentiate if there are multiple computers accessing from the same IP.
