WHMCS授权及更新检查工具 - 网页阁吧

之前一直有童鞋抱怨说由于忘记为WHMCS续费，导致后台因欠费被禁止登录的问题。

笔者写了一个小工具，用于检查WHMCS授权合法性及最新版本。该工具可与WHMCS同时工作，自动从数据库中读取版本和授权信息，无需人工干预。

部署说明

1. 将LicenseCheck.php保存在WHMCS的根目录下，class.smtp.custom.php保存在/includes/classes下；

2. 根据实际情况修改LicenseCheck.php的高亮代码行；

3. 将LicenseCheck.php添加为计划任务定时执行。

4. 如需禁用该工具，可以在WHMCS的根目录下/configuration.php中增加（设置为true则启用）：

$license_check = false;
