PHP Curl Do While Loop on Pagination with Limit and Offset - php

Question

I am newbie here and want to ask about PHP loop
I want to get 'itemid' from myendpoint and store it to $result_array
Myendpoint has pagination
First page, offset=0, second page, offset=100, etc
Maximum itemid on first page is 100, second page is 100, etc
The last page is unknown, so I set count($result_array) % 100 == 0 as while condition
The logic is if first page contain 100 itemid, do second page, if second page contain 100 itemid, do third page, etc
My script only work if first page contain < 100 itemid and there is no second page
How to solve this?
Thank you.
this is my script:
$limit = 100;
$offset = 0;
$result_array = array();
$url = 'https://myendpoint/?limit=' . $limit . '&offset=' . $offset;
do {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$response = curl_exec($ch);
$data = json_decode($response, true);
curl_close($ch);
$itemIds = array();
foreach ($data["items"] as $row) {
$itemIds[] = $row["itemid"];
}
$result_array = array_merge($result_array, $itemIds);
$offset = $offset + $limit;
} while (count($result_array) % 100 == 0);
print_r($result_array);

Pretty simple error: you use the same URL over and over, as you build it outside your loop. Move it into your loop, such that it contains the $offset you are calculating within that loop
