I Have one string which contains the link of prev and next page link:

Link: "<https://{shop}.myshopify.com/admin/api/{version}/products.json?page_info={next_page_info}&limit={limit}>; rel={next}, <https://{shop}.myshopify.com/admin/api/{version}/products.json?page_info={prev_page_info}&limit={limit}>; rel={previous}"

expecting output

array(
    'next' => {next_page_info},
    'prev' => {prev_page_info}
);

link string has also some condition as below:

string has both next and prev link
string has only next link Output should be array(‘next’ => ‘{next_page_info}’ );
string has only prev link Output should be array(‘prev’ => ‘{prev_page_info}’);

You can try this function I wrote just send it the links text or the whole header info

 private function render_links($Link)
    {
        $combined_links = [];
        $links = explode(',', $Link);
        foreach ($links as $link){
            if (preg_match('#<(http(?:s)?://.*.myshopify.com/.*products.json?.*)>;.*rel=\"(.*)\"#', $link, $matches)) {
                $combined_links[$matches[2]] = $matches[1];
            }
        }

        return $combined_links;

    }

it will return the links like this as array

"previous":"limit=1&fields=id%2Cimages&page_info=eyJkaXJlY3Rpb24iOiJwcmV2IiwibGFzdF9pZCI6NDA5OTUyMjM5NjE5NSwibGFzdF92YWx1ZSI6InNmc2Rmc2YifQ",
"next":"limit=1&fields=id%2Cimages&page_info=eyJkaXJlY3Rpb24iOiJuZXh0IiwibGFzdF9pZCI6NDA5OTUyMjM5NjE5NSwibGFzdF92YWx1ZSI6InNmc2Rmc2YifQ"

To return page_info for all types of URL.

public function parsePaginationLinkHeader ($headerLink) 
{

    $available_links = [];
    $links = explode(',', $headerLink);
    foreach ($links as $link){

        if (preg_match('/<(.*)>;srel=\"(.*)\"/', $link, $matches)) {

            $query_str = parse_url($matches[1], PHP_URL_QUERY);
            parse_str($query_str, $query_params);
            $available_links[$matches[2]] = $query_params['page_info'];
        }
    }

    return $available_links;
}
