Answer 1

Here is my solution to get the next and previous links from Shopify's Link Response Header:

Let's suppose you got the link header in:

$link_headers = '<https://xxx.myshopify.com/admin/api/2022-10/collections/id/products.json?
limit=50&fields=id,tags&page_info=XYXYXY>;
rel="previous",<https://xxxx.myshopify.com/admin/api/2022-10/collections/id/products.json?
limit=50&fields=tags&page_info=XYXYXYZ>; rel="next"';

Then you can use:

$links_arr = explode(", ", $link_headers);
    
$cursor_links = [];

for($i=0; $i < count($links_arr); $i++) {
    $tmp = explode('; rel=', $links_arr[$i]);
    $cursor_links[trim($tmp[1], '"')] = substr($tmp[0], 1, -1);
}

var_dump($cursor_links); 

Which returns:

array(2) {

   ["previous"]=> "https://xxx.myshopify.com/admin/api/2022-10/collections/id/products.json?
                   limit=50&fields=tags&page_info=XYXYXY",

   ["next"]=> "<https://xxx.myshopify.com/admin/api/2022-10/collections/id/products.json?
               limit=50&fields=tags&page_info=XYXYXYZ"

}
