importar un archivo csv desde un sitio FTP externo

Question

Tengo el siguiente script para importar datos de un archivo csv en mi servidor, el script funciona correctamente.

Necesito cambiar la ubicación del archivo de mi servidor a un servidor FTP que requiere autenticación. El nombre del archivo csv en el servidor FTP aparecerá de acuerdo con la marca de tiempo en que se generó. Después de importar a la base de datos MySQL, el archivo en el servidor FTP necesita ser eliminado.

Necesito programar este trabajo con trabajos cron para que se ejecute cada 5 minutos.

Cualquier ayuda será apreciada.

Gracias.

pensé que iba a publicar simplemente el código que resuelve mi problema; descarga un archivo csv desde un sitio FTP externo a mi servidor local. A continuación, importa el archivo csv en mi tabla de base de datos mysql local. Una vez importado, el archivo en el servidor ftp se elimina. Programo este trabajo en cpanel con cronjob.

No me puedo atribuir el mérito del guión, acabo de modificar un guión encontrado en otro sitio. Estoy seguro de que hay mejores formas de hacerlo con algunas comprobaciones de errores. Sin embargo, esto es lo mejor que puedo hacer con mis habilidades limitadas.

Espero que esto ayude a los futuros visitantes con el mismo problema. Gracias a todos los que me asistieron. Aquí está el código que utilicé:

<?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";
