PHP ftp_put fails

I use PHP to upload images from a host into FTP remote server.
I have already stored the names of the files that need to be uploaded to the FTP remote server, stored on the database.
After connecting to DB and a query for select information of images, I passed variables with $_SESSION to another PHP file for upload them on FTP remote server like this:
conn_auth.php for select target images:
<?php
if (file_exists(__DIR__.'/conn_auth/db_conn.php')){
include __DIR__.'/conn_auth/db_conn.php';
}else{
die('Connection is Failed ...!');
}
$conn = OpenConn();
$sql = "SELECT * FROM users where status = 'Active'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$user_id = $row["id"];
//search for user_id in userAthentication Table in DB
$sql = "SELECT * FROM userauthentication where user_id = $user_id";
$result = $conn->query($sql);
$user_auth = $result->fetch_assoc();
$user = array(
'id'=>$row['id'],
'name'=>$row['name'],
'family'=>$row['family'],
'auth_image'=>'',
'file_name'=>$user_auth["image"],
'phone'=>$row["phone"]
);
$url = "/home/root/app_name_1/uploads/".$user["file_name"];
if(!file_exists($url)){
$url = "/home/root/app_name_2/uploads/".$user["file_name"];
}
$user['auth_image'] = $url;
session_start();
$_SESSION["userInfo"] = $user;
$_SESSION["userAuth"] = $user_auth;
if (file_exists(__DIR__.'/conn_auth/get_auth.php')){
include __DIR__.'/conn_auth/get_auth.php';
}else{
die("I can't Connect to the Server");
}
}
} else {
echo "0 results";
}
CloseConn($conn);
On this file, I try to connect to FTP remote server and upload images with the ftp_put() method, but it does not work:
<?php
include_once __DIR__.'../conn_auth.php';
session_start();
$ftp_server="*.***.***.**";
$ftp_user_name="****";
$ftp_user_pass="**********";
$file = $_SESSION["userInfo"]['auth_image']; //to be uploaded
$folder_name = $_SESSION["userInfo"]['phone'];
$file_name = $_SESSION["userInfo"]["file_name"];
$remote_file = "/HDD/pics/$folder_name";
$conn_id = ftp_connect($ftp_server,21);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
ftp_mkdir($conn_id,'auth_pics').ftp_chdir($conn_id,'auth_pics');
if (ftp_mkdir($conn_id,"$folder_name")){
ftp_chdir($conn_id,$folder_name);
}else{
echo "I Can't Create Folder For : ".$folder_name;
die();
}
// upload a file
$upload = ftp_put($conn_id, $remote_file, $file, FTP_BINARY);
if ($upload) {
echo "successfully uploaded : $file\n";
} else {
echo "There was a problem while uploading...\n";
}
// close the connection
ftp_close($conn_id);
?>

Mostly your FTP server doesn't support active mode connections, so you may try to switch to the passive mode using the ftp_pasv, but make sure to do this after you logged into the server (after ftp_login).
If you face some troubles while using the native API functions, you may want to try out an FTP client library, like this, that I've built.
Hope you find this answer useful for you.
