PHP cURL add pagination using foreach loop - php

Question

I am using the attached script to output 100 results at a time from an XML file. The total record count e.g 1000 is held in $totalRecordCount = $oXML['total_record_count']; The user enters a search term in a form and results get outputted on same page. Each result is a link to a detail page. How do I integrate pagination in it if there's a 1000 results 1|2|3...10? I tried integrating something as per Simple pagination for foreach loop with no success however. Any help appreciated. Thanks
<?php
if (isset($_GET['submit2'])) {
$search2 = preg_replace('/\s+/', '+', $_GET["dept-keywords"]);
$sanitizeSearch2 = filter_var($search2, FILTER_SANITIZE_STRING);
echo '<b>Results: ' . $_GET["dept-keywords"] . '</b>';
$ch = curl_init();
$baseUrl = 'https://example.com/';
$templateParamNames = array('{user_id}');
$templateParamValues = array(urlencode('exl_impl'));
$baseUrl = str_replace($templateParamNames, $templateParamValues, $baseUrl);
$queryParams = array(
//info
);
$url = $baseUrl . "?" . http_build_query($queryParams);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
$oXML = new SimpleXMLElement($response);
echo '<ol>';
$totalRecordCount = $oXML['total_record_count'];
$count = 0;
foreach ($oXML->user as $user) {
$first_name = $user->first_name;
$user_link = strtolower("https://example.com/" . $first_name);
echo '<li>';
echo "<a href='" . $user_link . "'> " . $first_name . " </a>" . "\r\n";
echo '</li>';
$count++;
}
if ($count == 0) {
echo '<label>Sorry, no results!</label>';
}
echo '</ol>';
curl_close($ch);
}
