Php Simple Html Dom Parser無法獲取分頁內容

Question

嗨，我是一名初學者，使用simple_html_dom。我試圖從這個示例網站的帖子列表中獲取href列表，並使用下面的代碼進行分頁。

<?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

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/853-lightbright-elegantthemes-wordpress-theme.html

http://www.themelock.com/wordpress/795-elegantestate-real-estate-elegantthemes-wordpress-theme.html 
http://www.themelock.com/wordpress/786-notebook-elegantthemes-wordpress-theme.html 

上面的代碼只讀取下一頁（第二頁）內容。我想知道如何獲得第一頁的網址後接下一頁。

有沒有人知道如何做到這一點？

感謝您的支持傢伙，我做了這個工作，使用下面的代碼，

<?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); 
} 

?>
