在php中读取URL

Question

我想检查请求来自哪个URL LIKE --- www.mysite.com or bussiness.mysite.com。我们如何检查它，因为$ _SERVER ['HTTP_HOST']提供了整个URL。 谢谢 。

Answer 1

$domain = $_SERVER['HTTP_HOST'];
$path = $_SERVER['SCRIPT_NAME'];

$url = "http://" . $domain . $path . "?" . $queryString;
echo "The current URL is: " . $url . "";

你想要的是你的网址的子域名。使用此

$subdomain =  array_shift(explode(".",$_SERVER['HTTP_HOST']));
