i want to pull the 30 out of the url only and not the other data

 

You can use preg_match, or you can use my own function below.

// Usage
$data = file_get_contents('...');
$string = between('<div id=test>', '</div>', $data);

function between($start, $end, $source) {
        $s = strpos($source, $start) + strlen($start);
        return substr($source, $s, strpos($source, $end, $s) - $s);
}

PHP:

 

you can use preg_match or preg_match_all too..

 

Thanks a lot ... works like a charm
