我有以下脚本从我的服务器上的csv文件导入数据,该脚本可以正常工作。
我需要将文件的位置从我的服务器更改为需要身份验证的FTP服务器。 FTP服务器上的csv文件名将根据生成的时间戳而变化。导入MySQL数据库后,需要删除FTP服务器上的文件。
然后我需要使用cron作业安排这项工作,每5分钟运行一次。
任何帮助将不胜感激。
感谢。

我以为我会发布解决我问题的代码;它将csv文件从外部FTP站点下载到我的本地服务器上。然后它将csv文件导入到我的本地mysql数据库表中。导入后,ftp服务器上的文件将被删除。我用cronjob在cpanel安排这份工作。
我不能赞成这个脚本,我刚刚修改了在另一个网站上找到的脚本。我确信通过一些错误检查有更好的方法。然而,这是我用我有限的技能做的最好的。
我希望这可以帮助未来的访问者遇到同样的问题。感谢所有帮助我的人。 这是我使用的代码:
<?php
$source = "DespGoods.csv";
$target = fopen("DespGoods.csv", "w");
$conn = ftp_connect("ftp.server.com") or die("Could not connect");
ftp_login($conn,"ftpusername","ftppassword");
ftp_fget($conn,$target,$source,FTP_ASCII);
echo "file downloaded.\n";
