regex - php preg_match_all numbers in parentheses

Question

I am trying to load a remote website and get all numbers that are inside of parentheses. But what ends up happening is it only matches the last value.

Is my regex wrong? Am I using the correct flags?

I have added the example of what it should match on in the second $html variable.

    //$html = file_get_contents("http://example.com/test.html");

    $html = "(1234) (12) (1)  
  (1346326)";
    preg_match_all("^[(d)]+$^", $html, $matches, PREG_PATTERN_ORDER);
    print_r($matches);
    echo "<br>";
    foreach ($matches as $val) {
        echo "matched: " . $val[0] . "
";

    }

Thanks.

How about:

preg_match_all("/((d+))/", $html, $matches, PREG_PATTERN_ORDER); 
print_r($matches[1]);
