How to get parameters from a URL string?

I created function from @Ruel answer. You can use this:

function get_valueFromStringUrl($url , $parameter_name)
{
    $parts = parse_url($url);
    if(isset($parts['query']))
    {
        parse_str($parts['query'], $query);
        if(isset($query[$parameter_name]))
        {
            return $query[$parameter_name];
        }
        else
        {
            return null;
        }
    }
    else
    {
        return null;
    }
}

Example:

$url = "https://example.com/test/the-page-here/1234?someurl=key&email=xyz5@test.com";
echo get_valueFromStringUrl($url , "email");

Thanks to @Ruel
