Downloading files from FTP failing - php

Question

I checked over some other answers before I came here to publish a question, I'm having trouble with the following script, no matter what i've tried it will not download a file from the FTP even after listing the files that are in directory (obviously)
Because I'm organised I like to simplify everything into a class,
class FTPHandler
{
private $connection;
public function FTPConnect($host, $user, $pass)
{
$ftp = ftp_connect($host);
$login = ftp_login($ftp, $user, $pass) or die("FTP: Login Failed");
if ($login) {
$this->connection = array("host" => $host, "user" => $user, "pass" => $pass);
return $ftp;
}
echo "FTP Login Failed";
}
public function ListAllFiles($stream, $dir)
{
ftp_pasv($stream, true);
$ls = ftp_nlist($stream, $dir);
return $ls;
}
public function get_conx_info() {
return $this->connection;
}
}
Using the following code:
define("APP_DIR", "./app/");
$ftp = new FTPHandler();
$handle = $ftp->FTPConnect("ftp.example.com.au", "exampleuser", "examplepass");
$files = $ftp->ListAllFiles($handle, APP_DIR);
foreach ($files as $val)
{
if ($val != "." && $val != ".." && $val != "processed") {
$local_file = $val;
$remote_file = APP_DIR.$val;
if (ftp_get($handle, $local_file, $remote_file)) {
echo "Successfully retrieved: $remote_file <br/>";
}
else
{
echo "Failed retrieving file: $remote_file <br/>";
}
}
}
My return is always:
Failed retrieving file: ./app/adsl-1989-csv.csv
Failed retrieving file: ./app/adsl-1989-sig.png
Failed retrieving file: ./app/dd-1964-csv.csv

Failed retrieving file: ./app/dd-1975-csv.csv
Failed retrieving file: ./app/dd-1975-sig.png

Any assistance is highly appreciated as I have to have this automated to alleviate a few thousand per week off the employee budget.

Answer 1

I ended up discovering that the FTP server itself was at fault.
The error was fixed by changing from the default Active Ports as it was dropping majority of packets.
So if anyone out there is experiencing the same issue, worth taking a look at doing the same.
Thank you to Fred -ii- for your attempt in assisting me.
