ftp_nb_continue

Definition and usage

The ftp_nb_continue() function continuously obtains/sends files.

This function returns the following values:

• FTP_FAILED (send/receive failed)
• FTP_FINISHED (send/receive completed)
• FTP_MOREDATA (send/receive in progress)

This function sends/gets files asynchronously. This means that your program can perform other actions when the file is downloaded.

实例

<?php
$source = "source.txt";
$target = fopen("target.txt", "w");

$conn = ftp_connect("ftp.testftp.com") or die("Could not connect");
ftp_login($conn,"admin","ert456");

$status = ftp_nb_fget($conn,$source,$target,FTP_ASCII);

while ($status == FTP_MOREDATA)
  {
  $status = ftp_nb_continue($conn);
  }

if ($status != FTP_FINISHED)
  {
  echo "Download error";
  }

ftp_close($conn);
?>
