reading a string

I want to have my php page email me or my 2nd email (i have future usage so just testing right now) based on the visitor ip.

is there a way to take getenv(HTTP_ADDR)
and then read it as a string.

basicly I want to be able to read the first 2 blocks.

i.e. 123.123.234.234 I want to read 123.123.

and then make a decision based on that who I email by setting a variable to 1 if main email or 2 if secondary email

my question is though how do I read
$ip = getenv(HTTP_ADDR);
as a string later on

$ip is the string you have declared. You can then create an array using the [ . ]'s between each octet:

$ip_array = explode("." , "$ip");

$ip_array[0] octet 1
$ip_array[1] octet 2
$ip_array[2] octet 3
$ip_array[3] octet 4

ok thanks

so I should be able to do a compare of

if ($ip_array[0] == "xx" && $ip_array[1] == "xx")
<my mail code here>;

right? or is there another way of doing compairs

If it's an exact match (which this is) yes.

cool, thanks a bunch

Anytime!
