我想将域名与网站URL匹配

Question

Suppose, I have an URL like http://www.example.com/page1.html . In my database I have domain like this http://example.com/ .

Now, if the domain name exists in the DB, I want to return that in the URL.

Answer 1

 $domain_name = parse_url('http://example.com/');
 if ($_SERVER['SERVER_NAME'] ==  $domain_name['host'])
 {
 // some thing here
  }

Answer 2

Spliting your answer into two parts:

1. ( php-how-to-get-the-base-domain-url )

   $_SERVER['SERVER_NAME'];

2. Checking if data exist in database

   $result = mysql_query('SELECT COUNT(*) FROM table WHERE field = ...'); if (!$result) { die(mysql_error()); } if (mysql_result($result, 0, 0) > 0) { // some data matched } else { // no data matched }
