Question

The code below seems to only return the first two digits of my IP address. How can I get the full IP address?

$ip2 = $_SERVER['REMOTE_ADDR'];

EDIT: I’m putting it into MySQL as varchar(30) latin1_swedish_ci. Is there a format change that will show the full IP?

EDIT 2: Maybe it’s my query that’s changing the format. Here it is:

$query1 = sprintf("INSERT INTO values VALUES (NULL, 'phoenix', %d, '%s', %d, %d, %d, NULL)", $submissionid, $fullurl, $uid, $ip1, $ip2);

mysql_query($query1) or die(mysql_error());

Answer 1

There is absolutely nothing wrong with

$ip2 = $_SERVER['REMOTE_ADDR'];

You say it only seems to contain the first two digits, but I’m guessing you made this assumption because $query1 only contains that.

The problem is that you’re using %d in sprintf() which attempts to get the integer value of $ip2. An IP address is not an integer, but a string, thus you should use %s.

sprintf("INSERT INTO values VALUES (NULL, 'phoenix', %d, '%s', %d, '%s', '%s', NULL)",
     $submissionid, $fullurl, $uid, $ip1, $ip2);
