Cannot run PHP this code on linux. Getting error_log

Hello, this code should .tar a folder and upload it to an external FTP.

$dir = '/testtt'; // Directory to backup.
$filename = 'backups/backup' . date("MdY") . '.tar'; //path to where the file will be saved.

$ftp_server = 'myserver'; //External FTP server
$ftp_user_name = 'myusername'; //External FTP server username
$ftp_password = 'password'; //External FTP server password

if(system("tar cvf $filename $dir")){
$conn_id = ftp_connect($ftp_server);

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_password);

if (($conn_id) || ($login_result)) {

$upload = ftp_put($conn_id, 'backups/' . date("MdY") . '.tar', $filename, FTP_BINARY);

    }
    
    
    ftp_close($conn_id);
} //Initial if statement  

PHP:

I am trying to run it with the following command:

php /backupscript.php

Code (markup):

But it doesn't work. In the error_log I see the following:

What does it mean?

IOW, uploadprogress.so is commented out in your php.ini file. Uncomment it. (If you're on a hosted site you may not have access to php.ini. In that case, call tech support at your host.)
