Domain name authorization code can be encapsulated into functions or encrypted. For commonly used PHP encryption forms have their own cracking methods, such as ZendGuard, ionCube, etc. If there are many authorized domain names, you can add a domain name field to the project, write the domain name into the database, and then read and verify it. We have published this method It becomes 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.

	//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){
