importera csv-fil från extern FTP-webbplats

Jag tänkte att jag bara skulle lägga upp koden som löste mitt problem; den laddar ner en csv-fil från en extern FTP-plats till min lokala server. Den importerar sedan csv-filen till min lokala mysql-databastabell. När filen har importerats på ftp-servern raderas den. Jag schemalägger det här jobbet i cpanel med cronjob.

Jag kan inte ta åt mig äran för manuset, jag har just modifierat ett manus som finns på en annan sida. Jag är säker på att det finns bättre sätt att göra detta med lite felkontroll. Detta är dock det bästa jag kunde göra med mina begränsade färdigheter.

Jag hoppas att detta hjälper framtida besökare med samma problem. Tack till alla som hjälpte mig. Här är koden jag använde:

$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";
