Just call the following function:

function getQueryParameter($url, $param) {
    $parsedUrl = parse_url($url);
    if (array_key_exists('query', $parsedUrl)) {
        parse_str($parsedUrl['query'], $queryParameters);
        if (array_key_exists($param, $queryParameters)) {
            return $queryParameters[$param];
        }
    }
}

Example:

• $parameter = getQueryParameter('https://www.mohsin.com?main=17&street=71', 'main') will return 17.
• $parameter = getQueryParameter('https://www.mohsin.com?main=17&street=71', 'street') will return 71.
• $parameter = getQueryParameter('https://www.mohsin.com?main=17&street=71', 'invalid') will return null.
