PHP check if referring url has variable

I am using the below to get the referring URL but what I would like to check is whether $ref has a variable in it.

Referring Link http://domain.com/?s=checking

Current Link http://domain.com/product/cheese

Ideally I would like to be able to use PHP to check if the variable $ref has the GET Variable s in it

PHP

$ref = $_SERVER['HTTP_REFERER'];

$queryParams = parse_url($ref, PHP_URL_QUERY);
if ($queryParams) {
    parse_str($queryParams, $values);
    if (isset($values['s'])) { 
        echo 'Has query param s: ', $values['s'];
    }
}
