ftp_put()实例

更新日志

参见

• ftp_pasv()返回当前 FTP 被动模式是否打开
• ftp_fput()上传一个已经打开的文件到 FTP 服务器
• ftp_nb_fput()将文件存储到 FTP 服务器（非阻塞）
• ftp_nb_put()存储一个文件至 FTP 服务器（non-blocking）

ftp_put() overwrites existing files. 
Again: trivial but not mentioned here.

If when using ftp_put you get the one of the following errors:
Warning: ftp_put() [function.ftp-put]: Opening ASCII mode data connection
Warning: ftp_put() [function.ftp-put]: Opening BINARY mode data connection
and it creates the file in the correct location but is a 0kb file and all FTP commands thereafter fail. It is likely that the client is behind a firewall. To rectify this use:

Before executing any put commands. Took me so long to figure this out I actually cheered when I did :D

If you want to copy a whole directory tree (with subdiretories), 
this function (ftp_copy) might be usefull. Tested with 
php 4.2.2 and a Linux OS. 
Example:
----------------------------------------------------------------
$conn_id = ftp_connect("server_adress"); 
...
$src_dir = "/from";
$dst_dir = "/to";
ftp_copy($src_dir, $dst_dir);
...
ftp_close($conn_id)
Function: ftp_copy()
----------------------------------------------------------------
function ftp_copy($src_dir, $dst_dir) {
global $conn_id;
$d = dir($src_dir);
  while($file = $d->read()) {
    if ($file != "." && $file != "..") {
      if (is_dir($src_dir."/".$file)) {
        if (!@ftp_chdir($conn_id, $dst_dir."/".$file)) {
        ftp_mkdir($conn_id, $dst_dir."/".$file);
        }
      ftp_copy($src_dir."/".$file, $dst_dir."/".$file);
      }
      else {
      $upload = ftp_put($conn_id, $dst_dir."/".$file, $src_dir."/".$file, FTP_BINARY);
      }
    }
  }
$d->close();
}

If you are having timeouts uploading a file, even very small files, you might have a look at ftp_pasv()
And don't forget to do it after your ftp_login();

Here is a fix for the function from lucas at rufy dot com below that will recursively put files from a source directory to a destination directory. As written below, it won't put a file in a directory that already exists, because the the destination is altered. So here is the corrected function that will allow it to work:
function ftp_putAll($conn_id, $src_dir, $dst_dir) {
  $d = dir($src_dir);
  while($file = $d->read()) { // do this for each file in the directory
    if ($file != "." && $file != "..") { // to prevent an infinite loop
      if (is_dir($src_dir."/".$file)) { // do the following if it is a directory
        if (!@ftp_nlist($conn_id, $dst_dir."/".$file)) {
          ftp_mkdir($conn_id, $dst_dir."/".$file); // create directories that do not yet exist
        }
        ftp_putAll($conn_id, $src_dir."/".$file, $dst_dir."/".$file); // recursive part
      } else {
        $upload = ftp_put($conn_id, $dst_dir."/".$file, $src_dir."/".$file, FTP_BINARY); // put the files
      }
    }
  }
  $d->close();
}

The following is a fully tested function (based on a previous note) that recursively puts files from a source directory to a destination directory. See http://rufy.com/tech/archives/000026.html for more information.
NOTE: use full path name for the destination directory and the destination directory must already exist
function ftp_putAll($conn_id, $src_dir, $dst_dir) {
  $d = dir($src_dir);
  while($file = $d->read()) { // do this for each file in the directory
    if ($file != "." && $file != "..") { // to prevent an infinite loop
      if (is_dir($src_dir."/".$file)) { // do the following if it is a directory
        if (!@ftp_chdir($conn_id, $dst_dir."/".$file)) {
          ftp_mkdir($conn_id, $dst_dir."/".$file); // create directories that do not yet exist
        }
        ftp_putAll($conn_id, $src_dir."/".$file, $dst_dir."/".$file); // recursive part
      } else {
        $upload = ftp_put($conn_id, $dst_dir."/".$file, $src_dir."/".$file, FTP_BINARY); // put the files
      }
    }
  }
  $d->close();
}

Hi !
If you get this error when trying to send data to server :
Warning: ftp_put() [function.ftp-put]: Unable to build data connection: Connection timed out...
Two solutions :
 - Add the program httpd.exe in your exception list for external connexions of your firewall. Indeed, the FTP protocol open a new socket for data transfer. And this socket is opened from the server to the client (your computer). This program is located (for WAMP) in C:\wamp\bin\apache\Apache[version]\bin\
 - Use the ftp_pasv() function to activate the passive mode. In this mode, it is the client who open the new socket to the server.

Got this cryptic error
Warning: ftp_put() [function.ftp-put]: 'STOR' not understood in 
C:\wamp\www\kevtest\ftp_todays.php on line 48
Found the prob, you can't put a path to the destination file
(even though I can do that in the dos ftp client...?)
e.g. - this doesn't work
ftp_put($conn, '/www/site/file.html','c:/wamp/www/site/file.html',FTP_BINARY);
you have to put 

I [had an error for which] ftp_pasv didnt solve the problem. Here's why:
FTP uses 2 connections on different ports, one for connection/handshake and another for data transfer.
The problem was that the ftp-server (that php was connecting to) also used different IP-addresses for the different connections (say what!?).
Normally the firewall (csf) detects ftp-connections and allows them through but because of the different IP-adresses this didn't work.
Solution:
1 angry mail to the ftp server owner.
Allowing the second IP in the firewall.

if you examine the first user submitted function, ftp_putAll, it will work only if you extract this line and its matching bracket.
if (!@ftp_chdir($conn_id, $dst_dir."/".$file))
The function will have changed into that directory before having uploaded files to it. This alters your upload path and the system will try to upload into an essentially non-existent directory (duped at the end).
Hope this helps some of you.
Cheers.

Here is the Code I am using for the same function with more flexibility in static code: 

If you are getting the very helpful warnings...
"Opening BINARY mode data connection" or
"Opening ASCII mode data connection"
... and have tried ftp_pasv, ftp_alloc, switching between FTP_ASCII or FTP_BINARY and blaming the FTP provider (like I did), try using ftp_close then ftp_connect to reset your FTP connection. Worked for me!

Took me forever to work out but this will work if you get the paths right!

Login to your site using an FTP client to retrieve the $ftp_root
Use something like getcwd() to get the $site root

-----FTP PUT contents (php 7.0) ---
$tmpFile = tmpfile();
fwrite($tmpFile, $contents);
rewind($tmpFile);
$tmpMetaData = stream_get_meta_data($tmpFile);
if (ftp_put($ftpObj, $remoteFile, $tmpMetaData['uri'], FTP_ASCII)) {
   echo "success";
}else {
    echo "fail"
}
fclose($tmpFile);

I'm copying fairly large backup files from server to server. ftp_put was running fine for awhile until it occasionally began reporting errors.
When I set TRUE as the value for the ftp_pasv () (after login), ftp_put started working again.

Hi,
I try to upload one text file represente CSV with tab separator thru FTP connection.
i'm using :
ftp_put($connect_id, $fileFullName, $localFile, FTP_ASCII);
everything goes fine, but txt file in destination server get white line between dataline...
i try :
ftp_put($connect_id, $fileFullName, $localFile, FTP_BINARY);
and everything goes fine.
so, lets do it in binary mode.

This solution to a common problem is implied elsewhere, but I thought it might be useful to put it all in one place (since I spent hours piecing it together!)
Sometimes a web host will open PHP sessions with a user of 'nobody'. Files created by this user may not have the correct permissions to allow management of those files by the actual owner of the site. The following script allows the actual owner to open access to a directory so that 'nobody' can create a file using fopen(). Then using the handle created by 'nobody', the ftp_fput() command saves the file with the correct owner. The file 'nobody' created is discarded. 

Friends,
If you wanna upload files from your harddisk by a form to a specified ftp this sample can help you...
First of all create the form:   Image: 
     
The critical point in this form is the usage of enctype="multipart/form-data"
If you don't use this part your upload operations won't work.
Then u must create sendimage.php as follows:

In this example code $source_file is the path of the file in your disk, and destination file is the name of the uploaded file in ftpserver.
In this code I use ftp_chdir to give the path of the
 uploaded file within ftpserver..
