Question

How can I extract 4 from this string?

$string = "Rank_1:1:4";

I’m trying to get pagerank from Googles server, and the last value (4) is the actual pagerank.

Answer 1

Try

$string = "Rank_1:1:4";
$data = explode(':',$string);
echo end($data);

EDIT

as per @MichaelHampton, if they add more fields later, then use as below

$string = "Rank_1:1:4";
$data = explode(':',$string);
echo $data[2];
