Which are strings... You with me OK so far ?
Numeric [float] values only have 1 period.
There's no numeric datatype which has 3.

No, it isn't. It's an array of strings which has numeric indices
(or keys depends what you call em)

Yes, you should : They're strings unless you use inet_pton to convert
them to numeric values.

If you print_r($ips) you'll see the array structure (View -> Source
if you're looking at it in a browser).
My guess is your lines aren't terminated in \r\n, which PHP uses to
split the lines to array values.

You'll probably have to use some other method such as explode(',',
$ips) to break the individual comma separated entries into a set of
values. Other methods such as file_get_csv are generally more
efficient than reading line by line :

It's exactly like a CSV, from the example data you provided.
PS, please don't feel the need to prove it by posting the entire log file ;-)
