import csv-bestand van externe FTP-site

Ik dacht dat ik gewoon de code zou posten die mijn probleem oploste; het downloadt een csv-bestand van een externe FTP-site naar mijn lokale server. Vervolgens importeert het het csv-bestand in mijn lokale mysql-databasetabel. Eenmaal geïmporteerd wordt het bestand op de ftp-server verwijderd. Ik plan deze taak in cpanel met cronjob.

Ik kan het script niet met de eer strijken, ik heb zojuist een script op een andere site aangepast. Ik weet zeker dat er betere manieren zijn om dit te doen met wat foutcontrole. Dit is echter het beste wat ik kon doen met mijn beperkte vaardigheden.

Ik hoop dat dit toekomstige bezoekers met hetzelfde probleem helpt. Bedankt aan iedereen die me heeft geholpen.Hier is de code die ik heb gebruikt:

<?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";
