Почему simple_html_dom не запускается в цикле?

<?php
include('simple_html_dom.php');

for ($n = 1; $n < 215; $n++) {
    $html = new simple_html_dom();
    $html->load_file("http://site/" . $n . ".php");
    echo 'start ' . $n . ' <br>';
    $respCount = ($respCount = $html->find('tr'));

    for ($i = 0; $i < $respCount; $i++) {
        $respId = $html->find('tbody tr', $i)->children(0)->id;
        $respLan = $html->find('tbody tr', $i)->children(1)->plaintext;

        echo $respId;
        echo '=';
        echo $respLan;
        echo '<br>';
    }
    echo '<br>';
}
