PHP：如何使用cURL获取网页的基本URL [关闭]

Question

I'm trying to get contents of someone's web page remotely. The URL is something like:

http://www.somewebsite.com/post/slug-of-the-post/

And I want to get and display/output via PHP cURL is the base URL which is http://www.somewebsite.com/

What code to use should look like?

Answer 1

$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
$url_parts = parse_url($url);
echo $url_parts['scheme'].'://.'.$url_parts['host'];

This returns the URL in the current cURL session, parses the url, then displays the scheme and the host.
