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['HTTP_HOST']!='adcc.me')//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.
Code Encryption
The purpose of code encryption is to prevent some people with evil intentions.
There are many encryption methods, such as zend, md5 and so on. Put the key codes and authorization codes together and encrypt them!
