impor file csv dari Situs FTP eksternal

Saya pikir saya hanya akan memposting kode yang memecahkan masalah saya; itu mengunduh file csv dari situs FTP eksternal ke server lokal saya. Itu kemudian mengimpor file csv ke tabel database mysql lokal saya. Setelah diimpor, file di server ftp dihapus. Saya menjadwalkan pekerjaan ini di cpanel dengan cronjob.

Saya tidak dapat mengambil kredit untuk skrip, saya baru saja memodifikasi skrip yang ditemukan di situs lain. Saya yakin ada cara yang lebih baik untuk melakukan ini dengan beberapa pemeriksaan kesalahan. Namun, ini adalah yang terbaik yang bisa saya lakukan dengan keterampilan saya yang terbatas.

Saya harap ini membantu pengunjung masa depan dengan masalah yang sama. Terima kasih kepada semua pihak yang telah membantu saya. Berikut adalah kode yang saya gunakan:

<?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";
