PHP API Paging loop - php

Question

I have this code
I need a loop to be able to print all results which are 400-600 but I'm not able because I'm limited to only 100 shows per page and I need a loop/while to make the same request but changing the page and then print the result and I'm not able to make it, can someone explain me how to implement here a loop or to give me some examples?
<?php
include('config/config.php');
$ch = curl_init();
$username = '**************';
$password = ''**************';';
$hash = base64_encode($username . ':' . $password);
$headers = array(
'Authorization: Basic ' . $hash
);
$query = $connection->query("SELECT id_xyz_ro as prods FROM stock_prods where id_xyz_ro > 0");
$array = Array();
while($result = $query->fetch_assoc()){
$array[] = $result['prods'];
}
$connection->query('SET session group_concat_max_len=15000');
foreach($connection->query("SELECT GROUP_CONCAT(CONCAT('\'', id_xyz_ro, '\'')) as prods FROM stock_prods where id_xyz_ro > 0") as $row) {
}
$datas = array(
'id' => $array,
'itemsPerPage' => '100', //Only 100 because API it's limiting me at 100 shows per page
'currentPage' => '1' //Here I need to loop
);
$data = array(
'data' => $datas
);
set_time_limit(0);
$url = "www.xyz.net/api-3/product_offer/read";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
print_r($result); //After loop I need to print results from all loops
?>
Thanks in advance
