Is there a way to interpret multi-parameter query strings in Laravel?

Question

Is there a way to interpret multiple parameters from a query string that resembles the following?

sort=key1:asc,key2:desc,key3:asc

If not, is there a better strategy for passing sort parameters using query strings?

You can implement this or use something existing to build rest requests that translate to queries like graphql, json api and then some. — online Thomas

Not tested. In a Controller:

private function parseSortFromQueryString($sortStringToParse) 
{
  $sort = [];
  if(preg_match_all('/([a-zA-Z0-9_]+)(:(asc|desc))?/', $sortStringToParse, $matches, PREG_SET_ORDER)) {
    foreach($matches as $match) {
      $sort[$match[1]] = $match[3] ?? 'asc';
    }
  }
  return $sort;
}

public function index(Request $request) 
{
  $sort = $this->parseSortFromQueryString($request->input('sort', []));
  /* With your example
   * $sort = [
   *   key1 => asc
   *   key2 => desc
   *   key3 => asc
   * ]
   */
}
