I fiddled with this question for a server-side php  running from Linux terminal   I exploded  ifconfig  and trimmed it down to the IP address   Here it is    interface to detect    wlan0   echo explode     explode     explode  inet addr  explode  interface to detect trim  ifconfig    1   1   1   0     And of course change  wlan0  to your desired network device   My output is   192 168 1 5

This is an old post  but get it with this   function getLocalIp     return gethostbyname trim  hostname         For example   die  getLocalIp        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   gethostbyname trim  hostname       Is very similar  but much more efficient  than doing    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

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   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   socket connect will not cause any network traffic because it s an UDP socket

hostname 1  can tell the IP address  hostname --ip-address  or as man says  it s better to use hostname --all-ip-addresses

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   SERVER  SERVER ADDR     If PHP is being run through a command line interface  then you would likely have to shell-execute ipconfig  Windows    ifconfig   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
