ftp_get giving error while fetching a file - php

Question

Im trying to fetch a csv file from a remote server with ftp_get
$conn_id = ftp_connect($ftp_server);
ftp_pasv($conn_id, TRUE);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
$okk=0;
// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) (line 31)
{
$okk=1;
}
but its giving following error
Warning: ftp_get(): Opening BINARY mode data connection for /abc/abc.csv(198528 bytes). in /home/a/b/c/cm_data/d.php on line 31
I tried changing it to ascii mode then too it gave error
Warning: ftp_get(): Opening ASCII mode data connection for /abc/abc.csv(198528 bytes). in /home/a/b/c/cm_data/d.php on line 31
i also tried using ftp_pasv($conn_id, TRUE); too but still gives error.
What is the problem please help!!

Answer 1

ftp_pasv needs to be called after ftp_login!

Answer 2

You seem not to treat error cases from ftp_connect and ftp_login.
Please try the following code and see if it gives some errors:
<?php
$ftp_server = $ftp_server;
$ftp_user = $ftp_user_name;
$ftp_pass = $ftp_user_pass;
// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");
// try to login
if (#ftp_login($conn_id, $ftp_user, $ftp_pass)) {
echo "Connected as $ftp_user#$ftp_server\n";
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
$okk=1;
}
} else {
echo "Couldn't connect as $ftp_user\n";
}
// close the connection
ftp_close($conn_id);
?>
