php - 如何获取外部网站的基本 URL

Question

我正在使用 cURL 从外部站点返回数据。如何使用 PHP 返回站点的基本 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

我只想要http://www.bestbuy.com

谢谢!

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

//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
)
