you can put data array use loop

use code

$web = ['www.firstsite.com','www.secondsite.com'] $user = ['firstuser','seconduser'] $pass = ['firstpass','secondpass']  for($i=0;$i<sizeof($web);$i++) { $conn_id = ftp_connect($web[$i]); $login_result = ftp_login($conn_id,$user[$i],$pass[$i]);  if (ftp_put($conn_id, $server_file, $local_file, ftp_binary))  {echo "success";}  else {echo "failed";} }
