file_get_contents array foreach

Здравствуйте ! Прошу помочь Основная проблема тут как считаю я

foreach (file_get_html($links,true) as $lik) {
    foreach ($lik->find('.iteminfo-item-border .iteminfo-title-2 a') as $aa) {
        $linksa[] = "http://kotlant.ua" . $aa->href;
    }
}

Вот весь код

include "simple_html_dom.php";
ini_set('allow_url_fopen','1');

// Получаем ссылки на товары
$html_category = file_get_html('http://kotlant.ua/kg/tverdotoplivnye-kotly/');
$links = array();
// Получаем ссылки на товары с предложениями
foreach($html_category->find('.itemcat-item-border .item-cat-button a') as $a) {
    $links[] = "http://kotlant.ua".$a->href;
}
echo "<pre>";
print_r($links);
echo "</pre>";
echo "Товаров - ".count($links);
foreach (file_get_html($links,true) as $lik) {
    foreach ($lik->find('.iteminfo-item-border .iteminfo-title-2 a') as $aa) {
        $linksa[] = "http://kotlant.ua" . $aa->href;
    }
}
echo "<pre>";
print_r($linksa);
echo "</pre>";
echo "Товаров - ".count($linksa);
