My hamble improvements to the famouse `unparse_url` function by "thomas at gielfeldt dot com":

```php
    /**
     * @param array $parsedUrl -- result of the library `parse_url()` function
     *
     * @return string
     */
    function unparseUrl(array $parsedUrl): string
    {
        // PHP_URL_SCHEME
        $scheme = empty($parsedUrl[PHP_URL_SCHEME]) ? '' : (rtrim($parsedUrl['scheme'], ':/') . '://');

        $user = empty($parsedUrl[PHP_URL_USER]) ? '' : rtrim($parsedUrl['user'], '@:');
        $pass = empty($parsedUrl[PHP_URL_PASS]) ? '' : (':' . trim($parsedUrl['pass'], '@:'));

        $pass = !$user ? '' : ($pass . '@');

        $host = empty($parsedUrl[PHP_URL_HOST]) ? '' : rtrim($parsedUrl['host'], '/');
        $port = empty($parsedUrl[PHP_URL_PORT]) ? '' : (':' . (int)ltrim($parsedUrl['port'], ':'));
        $path = empty($parsedUrl[PHP_URL_PATH]) ? '' : ('/' . ltrim($parsedUrl['path'], '/'));

        $host = ($host && !$port && !$path) ? $parsedUrl['host'] : $host;
        $path = ($path && !$host && !$port) ? $parsedUrl['path'] : $path;

        $query = empty($parsedUrl[PHP_URL_QUERY]) ? '' : ('?' . ltrim($parsedUrl['query'], '?'));
        $fragment = empty($parsedUrl[PHP_URL_FRAGMENT]) ? '' : ('#' . ltrim($parsedUrl['fragment'], '#'));

        return "$scheme$user$pass$host$port$path$query$fragment";
    }
```
