Php Simple Html Dom Parser can't get content on pagination

问题

Hi i'm a beginner in using simple_html_dom. i'm trying to fetch list of href's from list of posts from this sample website having pagination using below code.

<?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);
}

?>

As a result i'm getting

Above code fetching only Next page (Second page) contents. I'm wondering how to get first page post url's followed by next pages.

Did anyone know how to do this ?

Thanks for your support guys, I made this to work using below code,

<?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);
}

?>
