How to get all the configured IPs of the machine?

I would like to know all the configured IPs addresses of the machine, can I get this information with PHP? I'm using linux, do not want to 开发者_StackOverflowuse this script on Windows.

Thank you!

You could parse the output of /sbin/ip addr

Edit: added /sbin/ip addr example. Here is an easy way to parse it.

ip addr |grep "inet" |grep -v "inet6" |cut -d"/" -f1 |cut -d" " -f6

1. Call ip addr
2. grep for lines "inet", excluding "inet6"
3. split the result on "/", this results in " inet XXX.XXX.XXX.XXX"
4. split the result on " ", take the 6th element, which should be the IP address.

Assuming your output looks something like mine, this should work fine. It is also pretty easy to tune if yours differs.

ifconfig |grep "inet addr" |cut -d: -f2 |cut -d" " -f1

For ifconfig output like the following:
