Where to put the php authorization code?

The purpose of domain name authorization: To protect intellectual property rights.

There are many ways to implement domain name authorization in php, such as:

1. Local verification method. (Recommended learning: PHP video tutorial)

2. Online verification method.

No matter which method is used, the principle is actually the same.

Today I will give an example of local verification!

Code implementation

<?php
if ($_SERVER[&#39;HTTP_HOST&#39;]!=&#39;adcc.me&#39;)//如果域名不是adcc.me
{
    echo "您的域名未授权，请联系购买正版产品！";}
?>

Note: can be specially set according to your own situation. If the verification fails, you can jump to the authorization page, or Contacts can be jumped. For specific methods, please consult Baidu.

The above code is based on authorizing the adcc.me domain name as an example.
