我正在使用cURL从外部站点返回数据.如何使用PHP返回网站的基本URL？

例如,我有这个URL: http://www.bestbuy.com/site/Insignia%26%23153%3B+-+55%22+Class+/+1080p+/+120Hz+/+LCD+HDTV/2009148.p?id=1218317000232&skuId=2009148

$url = "http://www.bestbuy.com/site/Insignia%26%23153%3B+-+55%22+Class+/+1080p+/+120Hz+/+LCD+HDTV/2009148.p?id=1218317000232&skuId=2009148";
echo "";
print_r(parse_url($url));


//Would give you
Array
(
    [scheme] => http
    [host] => www.bestbuy.com
    [path] => /site/Insignia%26%23153%3B+-+55%22+Class+/+1080p+/+120Hz+/+LCD+HDTV/2009148.p
    [query] => id=1218317000232&skuId=2009148
)
