How do I get the external IP of my server using PHP?

Question

I often hear people say to use \"$_SERVER[\'SERVER_ADDR\']\", but that returns the LAN IP of my server (e.g. 192.168.1.100). I want the external IP.

Answer 1

I think there is much code for this things in others answers, but my answer is short, but you need to execute a command in shell to get the ip...

but it is short and fast, I think that...

php execute bash > bash run > bash get ip > php get ip

echo shell_exec( "dig +short myip.opendns.com @resolver1.opendns.com");

Sorry my for my english, I hope it help all you...
