ftp_put() can display confusing warning messages as it returns one line of the remote server's response which may be multi lined.



If you're transferring large amounts of files note that some file systems only support up to 2000 files per directory. This had me stumped for a while.

I spent some time debugging a silly problem:



In php >= 5, ftp_put() will apparently rewind to the start of the file regardless of the state you left it in before sending it to the $host.



I found this out because I wasn't closing the file handle before using ftp_put(). Since I had just written to the file, the file pointer must have been located at the *bottom*.



I was sending a 0-byte file on php 4.2.2., but worked fine on php 5.



So, just a heads up, don't forget to close those filehandles. Even though I was using the filename as the argument for ftp_put, it still needs to be closed. 



I did not call rewind on the file handle, just fclose($file_h).

I had a little trouble getting the ftp_put to work, because of that particular server.  All variables and data parsed from the previous web form had to be retreived using $_POST, $_GET or $_FILES.



If you don't know what you sent use phpinfo(); to display what the server thinks about your data.



so...when sending files using a form and PHP, make sure that all the data (text files etc...) are retreived with $_POST, and files (smiley.png, compression.zip, etc...) are retreived with $_FILES.



here's what your start of a results.php file might look like:

<?PHP

   $myName = $_POST['name']; //This will copy the text into a variable

   $myFile = $_FILES['file_name']; // This will make an array out of the file information that was stored.

?>



Now when it comes to transmitting that information...



<?PHP

        $destination_path = "src/bin/"; 



//where you want to throw the file on the webserver (relative to your login dir)



    $destination_file = $destination_path."img.jpg";



//This will create a full path with the file on the end for you to  use, I like splitting the variables like this in case I need to use on on their own or if I'm dynamically creating new folders.



        $file = $myFile['tmp_name'];



//Converts the array into a new string containing the path name on the server where your file is.



    $upload = ftp_put($conn_id, $destination_file, $file, FTP_BINARY);// upload the file

    if (!$upload) {// check upload status

        echo "FTP upload of $destination_file has failed!";

    } else {

        echo "Uploaded $file to $conn_id as $destination_file";

    }

?>



hope this is usefull ^_^

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();

}

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.

<?

    $connection = ftp_connect($ftpServer);

    ftp_login($connection, $ftpUser, $ftpPass);

    ftp_chdir($connection, $ftpDir);

    // open the directory so that 'nobody' can create a temporary file    

    ftp_site($cn, "CHMOD 777 $ftpDir");

    $new="tempFile";

    @unlink($new); // just in case

    $handle=fopen($new,"x");

    chmod($new,0777);

    fputs($handle,"a bunch of stuff...");

    fclose($handle); // have to rewind 

    $handle=fopen("tempFile","r");

    ftp_fput($connection, "finalFile", $handle, FTP_ASCII);

    fclose($handle);

    unlink($new);

    // remove open access to the directory

    ftp_site($connection, "CHMOD 755 $ftpDir")

    ftp_close($connection);

?>

victor at nobel dot com dot br wrote that

the correct dirpath format excluded "/home/USER/" from the public path, but for my server, i had to use it in order to get my scripts to work.



it may be obvious to most but I'm positing that you cannot use the $_SERVER['DOCUMENT_ROOT'] path since FTP starts at your top-level and therefore bypasses (or just plain doesn't recognize) most of the virtual server pathing.

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.

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();

}

ftp_put() overwrites existing files. 

Again: trivial but not mentioned here.

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();

}

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:

<html>



<body marginwidth=4 marginheight=4 topmargin=4 leftmargin=4 bgcolor=white vlink="#0000ff" link="#0000ff">



<form name="Attachments"  method=POST action="sendimage.php" enctype="multipart/form-data">



<input type=hidden name=box value="">



<tr>

<td nowrap width="1%">&nbsp;&nbsp;<b>Image:</b></td>

<td colspan=2>

<input type=file name=source_file size=20> <br>



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;



</td>

</tr>

<input type=submit name=btnSubmit value=Submit size=20 style="border: 1px solid #0000FF"></form>

</body>

</html>



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:



<?php

        

    $ftp_server='190.148.20.201';//serverip

    $conn_id = ftp_connect($ftp_server); 

    

   

    // login with username and password

    $user="username";

    $passwd="*****";

    $login_result = ftp_login($conn_id, $user, $passwd); 



// check connection

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

        echo "FTP connection has failed!";

        echo "Attempted to connect to $ftp_server for user $ftp_user_name"; 

        die; 

    } else {

        echo "<br>Connected to $ftp_server, for user $user<br>";

    }

//directorylike /www.velibaba.com/images

  ftp_chdir($conn_id, "www.velibab.com");

  ftp_chdir($conn_id, "compimages");



//$destination_file=ftp_pwd($conn_id);



$destination_file="x.jpg";

echo ("<br>");

print $destination_file;



echo ("<br>");



// upload the file

$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 



// check upload status

if (!$upload) { 

        echo "FTP upload has failed!";

    } else {

        echo "Uploaded $source_file to $ftp_server as $destination_file";

    }



// close the FTP stream 

ftp_close($conn_id); 

?>



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..

When using versions of PHP below 4.04b4, the ftp_put command doesn't work on NT/IIS4. Most of the other functions will work, but there was a bug while trying to send upstream data to an IIS webserver.
