用PHP来自动发带附件的Email

阅读更多

我在做CS1010（Programming Methodology）的Tutor，其中一个任务是给学生作业判分，然后把判分的结果发给学生。

 

学生作业在我电脑里面folder的结构是：题号->学生学号->题目;其中题目为C code，有时候有其它的Tutor用Word判分之后会把结果发给我。

 

为了保护学生隐私，我需要分别给每个学生发送他的成绩，附上他的批改过的作业作为附件。于是，我可以用电脑来做这个重复而且麻烦的事情。

 

这里用的是PHP，以及它的Pear组件中的Pear_mail (用来发送email)，和pear_mime（用来给email加入附件）。学生的email就是学生学号@学校网址。

 

code见下（这里居然不能用PHP后缀作为附件！应该是因为怕上传上去自动执行PHP吧~）。我觉得这是一次很好的Programming Practice——把一些编程技巧拿来解决实际问题。

);
$from = "[email protected]";     // CONFIG your email address
$cc = "[email protected]";    // CONFIG the cc address    -- put your address so that you can confirm that the email has been sent successfully
$subject = "[CS1010] PE Mark";
