Php 无法每天生成自动邮件

我无法每天生成自动邮件。问题是它无法自动生成它。我有一种每天都会生成的代码。同样的细节。除了数据库查询之外，代码完全相同

这是我的密码：

    <?php
session_start();
require("../connect.php");

/* require files for MAIL */
require("class.phpmailer.php");
require("class.smtp.php");
/* require files for MAIL ENDS */

如果您希望定期或每天发送邮件，理想的方法是使用cron job发送邮件。通过使用cron，您可以指定希望cron在哪个应用程序上运行。此外，您还可以指定希望邮件发送的确切时间。
请参阅此处。
希望能有帮助
 在
$result=mysql\u查询（$query）之后使用
若要确定您的问题所在，请尝试打印SQL查询并在phpMyAdmin中进行测试。您实际上没有说明问题所在，也没有提供任何错误输出。
