[RESOLVED] Grab ONE Link from a website

[burstroo]

Hello,

I've kindof figured out the concept of going to a page and getting links, but I want to do this:

1. Go to the webpage
2. Grab one link (The 12th link found on the page)
3. Keep in my cache
4. Do my other functions
5. After I do my function .. go to that link..
6. Repeat it all over again but with that new link.

Here's a function that uses Snoopy to return the nth (array[n]) link from a page:

function nth_link($uri, $n)
{
    include_once 'Snoopy.class.php';
    $snoopy = new Snoopy;
    if($snoopy->fetchlinks($uri)) {
        $arr = $snoopy->results;
        if (isset($arr[$n])) {
            return $arr[$n];
        } else {
            return false;
        }
    } else {
        return false;
    }
}

Greatly appreciated. I've got it figured out now thanks to your help!
