PHP实现限制域名访问的实现代码(本地验证)

<?php 
if(!in_array($_SERVER['HTTP_HOST'],array('test.com','www.test.com'))){
	exit('建站请联系：http://www.test.com');
} 
?> 

function allow_domain(){
	$is_allow=false;
	$servername=trim($_SERVER['SERVER_NAME']);
	$Array=array("localhost","127.0.0.1","test.com","test1.com");
	foreach($Array as $value){
		$value=trim($value);
		$domain=explode($value,$servername);
		if(count($domain)>1){
			$is_allow=true;
			break;
		}
	}
	if(!$is_allow){
		die("<center>仅限本地使用！需要域名授权请联系jb51.net");
	}
}
allow_domain();

<?php
//获取不带端口号的域名前缀
$servername = trim($_SERVER['SERVER_NAME']);
//获取服务端授权文件校验
$verifyurl = file_get_contents('//www.jb51.net/zb_users/upload/copyright.php?domain='.$servername);
if(!empty($verifyurl)){
	echo "已授权！"; //授权成功
}else{
	die("未授权！"); //授权失败
}
?>

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

<?php
function allow_domain(){
	$is_allow=false;
	//获取不带端口号的域名前缀
	$servername=trim($_SERVER['SERVER_NAME']);
	//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();
