[RESOLVED] replace the last part of IP address with *** etc

[blackhorse]

For example if IP address is 64.12.34.56, I want to display it like 64.12.34.**

Here is my code

$this_ip="64.12.34.56";

	$this_sub_ip=substr($this_ip, 0, strrpos($this_ip, ".")+1);

	$this_sub_ip_replace_length=strlen($this_ip)-strlen($this_sub_ip);

	for ($index=0; $index<$this_sub_ip_replace_length; $index++)
	{
		$this_sub_ip=$this_sub_ip."*";
	}	

echo ($this_sub_id);

A little bit too much for a simple requests. I am looking for simpler solution if there is. Any advice?

Thanks!

$p = strlen($this_ip)-1;
while ($this_ip{$p} != '.') $this_ip{$p--} = '*';

seems to do the trick in a few less lines.
