我有一个import.php文件，它将csv文件中的数据导入数据库。 import.php的代码如下所示
<?php
include('db.php');
include_once "auth.php";

header("location: menu.php");
exit();
}

if(!$link){
die( "Sorry! There seems to be a problem connecting to our database.");

我希望在数据上传时触发邮件。所以我有邮件功能，将邮件发送给相关人员。我已将时间作为导入文件本身的一个列上传。任何人都可以建议我如何捕获上传的事件并触发该邮件功能。
<?php

//so we use the MD5 algorithm to generate a random hash

$headers = "From: txnportal.tnc@idea.adityabirla.com\r\nReply-To: txnportal.tnc@idea.adityabirla.com";

$attachment = chunk_split(base64_encode(file_get_contents($files[0])));
