Answer 1

Here it is. Look that I htmlspecialchars_decode the link. Cause the href in curl there shouldn't be an & like in xml. Should the return value of dlPage the last link in Pagination. I understood so.
<?php
include_once('simple_html_dom.php');
function dlPage($href, $already_loaded = array()) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_URL, $href);
curl_setopt($curl, CURLOPT_REFERER, $href);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.125 Safari/533.4");
$htmlPage = curl_exec($curl);
curl_close($curl);
echo "Loading From URL:" . $href . "<br/>\n";
$already_loaded[$href] = true;
// Create a DOM object
$dom = file_get_html($href);
// Load HTML from a string
$dom->load($htmlPage);
$next_page_url = null;
$items = $dom->find('ul[class="osh-pagination"] li[class="item"] a[title="Next"]');
foreach ($items as $item) {
$link = htmlspecialchars_decode($item->href);
if (!isset($already_loaded[$link])) {
$next_page_url = $link;
break;
}
}
if ($next_page_url !== null) {
$dom->clear();
unset($dom);
//load the next page from the pagination to collect the next link
return dlPage($next_page_url, $already_loaded);
}
return $href;
}
$url = 'https://www.jumia.com.gh/phones/';
$data = dlPage($url);
echo "DATA:" . $data . "\n";
And the output is:
Loading From URL:https://www.jumia.com.gh/phones/<br/>
Loading From URL:https://www.jumia.com.gh/phones/?facet_is_mpg_child=0&viewType=gridView&page=2<br/>
Loading From URL:https://www.jumia.com.gh/phones/?facet_is_mpg_child=0&viewType=gridView&page=3<br/>
Loading From URL:https://www.jumia.com.gh/phones/?facet_is_mpg_child=0&viewType=gridView&page=4<br/>
Loading From URL:https://www.jumia.com.gh/phones/?facet_is_mpg_child=0&viewType=gridView&page=5<br/>
DATA:https://www.jumia.com.gh/phones/?facet_is_mpg_child=0&viewType=gridView&page=5
