Problem with substr( ), Please Help me

[tony_l]

OK, here is my problem, and it should be be this difficult-

I am trying to SEARCH a MySQL Database for IP addresses that CLOSELY match each other.

Here is what is happening-

$checksum1 is the IP result from a mysql Record.

$checksum2 is where I am trying to get the first 6 characters of the IP address from checksum1.

Here is my dilemma- How can I can get CHECKSUM2 ? I have tried substr( ) with many different variables and it is not giving me the first 6 characters. Is there a function that can help me get just the first 6 characters of a string or is it possible?

thanks for your help.

$checksum2=substr($checksum1,0,6);
I think this should do it.
