Say I have a variable setting an ip address of 192.168.100.0 I want to be able to remove the last to chr's of that variable ie: .0 What would be my best solution to do that?

If you want the last two characters you can use substr():

[1]     $sResult = substr($sIP, -2);

If you want the string from the last period onward, regardless of length, you can use strrpos() and substr():

[2]     $iPos = strrpos($sIP, ".");
                if ($iPos !== FALSE) $sResult = substr($sIP, -$iPos);

Take the time to read about various string functions -- you'll thank yourself. http://php.net/strings Paul [1] substr http://php.net/substr see Example 2. Using a negative start [2] strrpos http://php.net/strrpos
