我之前没有使用过 $_SERVER['HTTP_REFERER']，我不知道如何使用它来通过点击 Google 搜索结果中的链接来找到访问我网站的用户.用户可以来自 google.com、google.co.uk 等......

推荐答案
$url = $_SERVER['HTTP_REFERER'];
$query = parse_url ($url, PHP_URL_QUERY);
$host = parse_url ($url, PHP_URL_HOST);
if (strstr ($query, 'q=') && strstr ($host, 'google.')) {
// user came from google
else {
// user didnt come from google
}
