I have an game ip in my database, like so: `"271.29.248.23:27912"`
I want the substring to take the last 5 numbers "`27912`" and also i want to delete the `":"`.
Is that possible and could someone help me?

And if possible i would like the numbers to be like this so it would be easier...

```
$ip = "271.29.248.23";
$port = "27912";

```

Please help me, i need this for a script :(
