Php Simple HTML Dom解析器無法獲得分頁內容

Question

嗨，我是使用simple_html_dom的初學者。 我正在嘗試使用以下代碼從具有示例性的該示例網站的帖子列表中獲取href列表。

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

$html = file_get_html('http://www.themelock.com/wordpress/elegantthemes/');

function getArticles($page) {

    global $articles;

    $html = new simple_html_dom();
    $html->load_file($page);

    $items = $html->find('h2[class=post-title]');  

    foreach($items as $post) {
        $articles[] = array($post->children(0)->href);
    }

    foreach($articles as $item) {
            echo "<div class='item'>";
            echo $item[0];
            echo "</div>";
        }
}

if($next = $html->find('div[class=navigation]', 0)->last_child() ) {
    $URL = $next->href;

    $html->clear();
    unset($html);

    getArticles($URL);
}

?>

結果我得到了

http://www.themelock.com/wordpress/908-minimal-elegantthemes-wordpress-theme.html
http://www.themelock.com/wordpress/892-event-elegantthemes-wordpress-theme.html
http://www.themelock.com/wordpress/882-askit-elegantthemes-wordpress-theme.html

http://www.themelock.com/wordpress/786-notebook-elegantthemes-wordpress-theme.html

上面的代碼僅提取下一頁（第二頁）的內容。 我想知道如何獲取首頁文章的網址，然后再獲取下一頁。

有人知道該怎么做嗎？

感謝您的支持，我使用下面的代碼來完成此工作，

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

$url = "http://www.themelock.com/wordpress/yootheme-wordpress/";

// Start from the main page
$nextLink = $url;

// Loop on each next Link as long as it exsists
while ($nextLink) {
    echo "<hr>nextLink: $nextLink<br>";
    //Create a DOM object
    $html = new simple_html_dom();
    // Load HTML from a url
    $html->load_file($nextLink);

    $posts = $html->find('h2[class=post-title]');

    foreach($posts as $post) {
        // Get the link
        $articles = $post->children(0)->href;        
        echo $articles.'</br>';
    }

    // Extract the next link, if not found return NULL
    $nextLink = ( ($temp = $html->find('div[class=navigation]', 0)->last_child()) ? $temp->href : NULL );

    // Clear DOM object
    $html->clear();
    unset($html);
}

?>
