Use file_get_contents($url) to get the HTML of the website in question.

 

Then loop through that content looking for <a tags. Each time you find an anchor tag, use substr() and strpos() to extract the link.

 

Do this for all links adding each one into an array. Once you've done this, go through each link checking to see whether it is from the domain you're looking for. You can use the parse_url() function to do this or you can use a combination of strpos() and substr()

 

If you need more information on the functions given above please see these links:

i think regular expressions are your friends for this ... using preg_match_all() and some fancy pattern you can get exactly what you need

[premiso]

<?php
$string = '<a href="http://www.abc.com/rand/file.r01"> <a href="http://www.abc.com/rand/file.r02"> <a href="http://www.abc.com/rand/file.r03">';

preg_match_all('~www.abc.com/(.+?)"~is', $string, $matches);

echo "<pre>" . print_r($matches, 1) . "</pre>";

die();
?>

 

Rough example. But should work.

 

Outputs:

Array
(
    [0] => Array
        (
            [0] => www.abc.com/rand/file.r01"
            [1] => www.abc.com/rand/file.r02"
            [2] => www.abc.com/rand/file.r03"
        )

    [1] => Array
        (
            [0] => rand/file.r01
            [1] => rand/file.r02
            [2] => rand/file.r03
        )

)
