您好我是使用simple_html_dom
的初学者。我正在尝试使用以下代码从此示例网站的帖子列表中获取href的列表。
<?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);
}
?>
结果我得到了
http://www.themelock.com/wordpress/908-minimal-elegantthemes-wordpress-theme.html
http://www.themelock.com/wordpress/892-event-elegantthemes-wordpress-theme.html

以上代码仅提取下一页(第二页)内容。我想知道如何获得第一页的网址后跟下一页。
有人知道怎么做吗?

感谢您的支持人员,我使用以下代码使其工作
<?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);
}
?>
