PHP parsing simple_html_dom

I am stuck with a semi-hard problem with 'simple html dom' (php class used for html parsing). I've used it many times before so I know how to do simple parsing. PROBLEM:

$k=0;
for ($k = 0; $k < 15; $k++)
{
    $link[$k] = 'www.example.com/' . $test[1][$k];
    print ($link[$k]);
    $test = file_get_html ('$link[$k]');
    echo($test);

What is the answer to this?

Variables in string declarations with single quotes are not expanded to the values they represent. So '$link[$k]' is actually the plain value $link[$k]. But actually you don’t need any quotes at all:

$test = file_get_html($link[$k]);

This seems to be the problem:

$test = file_get_html('$link[$k]');

Remove the quotes:

$test = file_get_html($link[$k]);
