php method to implement domain name authorization: first obtain the domain name prefix without a port number; then obtain the server authorization file for verification; then determine whether the authorization is successful; finally obtain the domain name and verify the result.

Two methods for PHP to implement domain name authorization

01. Method for online verification of domain name authorization:

Client code:

PHP

<?php
 
//获取不带端口号的域名前缀
 
$servername = trim($_SERVER[&#39;SERVER_NAME&#39;]);
 
//获取服务端授权文件校验
 
$verifyurl = file_get_contents(&#39;http://www.toyean.com/zb_users/upload/copyright.php?domain=&#39;.$servername);
 
if(!empty($verifyurl)){
 
echo "已授权！"; //授权成功
 
}else{
 
die("未授权！"); //授权失败
 
}
 
?>

Server code:

PHP

<?php
 
//获取域名
 
$domain = $_GET[&#39;domain&#39;];
 
//授权域名列表
 
$Array = array(&#39;127.0.0.1&#39;,&#39;localhost&#39;);
 
//校验结果
 
echo in_array($domain, $Array) ? &#39;yes&#39; : &#39;&#39;;
 
?>

The domain name authorization code can be encapsulated into a function or encrypted. There are methods to crack the commonly used PHP encryption forms, such as ZendGuard, ionCube, etc. If there are many authorized domain names, you can add a domain name field to the project to The domain name is written into the database and then read and verified. We have published this method as an independent plug-in. For details, see: ZBlogPHP Domain Name Authorization Plug-in-AllowURL. Through the plug-in, domain name and other information can be added to the database for verification.

02. Method to independently verify domain name authorization:

PHP

<?php
 
function allow_domain(){
 
$is_allow=false;
 
//获取不带端口号的域名前缀
 
$servername=trim($_SERVER[&#39;SERVER_NAME&#39;]);
 
//授权域名列表
 
$Array=array("localhost","127.0.0.1");
 
//遍历数组
 
foreach($Array as $value){
 
$value=trim($value);
 
$domain=explode($value,$servername);
 
if(count($domain)>1){
 
$is_allow=true;
 
break;
 
}
 
}
 
if(!$is_allow){
 
die("域名未授权！"); //授权失败
 
}else{
 
echo "域名已授权！"; //授权成功
 
}
 
}
 
allow_domain();
 
?>
