以下代码应向学习者发送电子邮件，但代码给我错误： “致命错误：在第46行的/home/train4/public_html/hocotest/cron-email-expire-1.php中调用未定义的方法mysqli_result :: fetch（）”
我将fetch（PDO :: FETCH_OBJ）替换为fetch_object（），然后文件运行正常，没有错误，但学习者没有收到电子邮件。 这封电子邮件有2部分， 1.它将发送电子邮件给学习者 2.向管理员发送电子邮件，告知系统的系统已向其发送电子邮件。
第二部分运行正常，管理员可以收到电子邮件，但是由于第1部分无法正常工作，因此系统没有向其发送电子邮件的信息。
我尝试运行没有数组的脚本，因此系统为每门课程发送1封电子邮件，如果学习者注册了7门课程，但未完成5门课程，则他们将收到5封电子邮件。但是我只想发送一封电子邮件，其中包含所有未完成的课程详细信息。

mysqli_result :: fetch_all（）需要MySQL本机驱动程序（mysqlnd）。
可能是您丢失了它。

以下是我能想到的最少的代码： $ strSQL_expire =“ SELECT * FROM tbl01user，tbl04usercourses，tbl03courses 在哪里a01User = a04UserId和a03CourseId = a04CourseId AND DATEDIFF（CURDATE（），a04StartDate）> 0 AND a04Completion = 0 AND a01UserRoll = 0 AND a01Status = 1 AND a04Status = 1“;

$nofinish = array();
$course = "";
$pre_email = "";
$pre_fn = "";
