我需要构建一个从 URL 解析域的函数.
I need to build a function which parses the domain from a URL.
所以,与
http://google.com/dhasjkdas/sadsdds/sdda/sdads.html
或
http://www.google.com/dhasjkdas/sadsdds/sdda/sdads.html
它应该返回 google.com
与

推荐答案
查看 parse_url()
:
$url = 'http://google.com/dhasjkdas/sadsdds/sdda/sdads.html';
$parse = parse_url($url);
echo $parse['host']; // prints 'google.com'
parse_url
不能很好地处理严重损坏的 url,但如果您通常期望得到不错的 url,那就没问题了.
parse_url
doesn't handle really badly mangled urls very well, but is fine if you generally expect decent urls.
