Keep in mind that ftp_get will overwrite the file on your local machine if it has the same name.

If you previously downloaded a file before (like a huge web log), and just want to get the remaining portion, do this:

$local_file_size = filesize($local_file_path);
$get_result = ftp_get($conn_id, $local_file_path, $remote_file_path, FTP_BINARY, $local_file_size);

This same code works regardless of wether the local file exists already or not.  You should first test to make sure the local file is not bigger than the remote file.

The zero size file is not a side effect.  When the ftp_get starts the first thing it does is to create the inode/file which it will stream the data too and that is a zero size file with the nname you specified for the local file.  When the download fails it leaves the file in place.

Hello everybody,

If someone will try to download files to the same local file (some temporary file), like shown here:

<?php
foreach ($files as $key=>$path) {
... 
 
$result ftp_get($ftpConnId'temp.tmp'$pathFTP_BINARY);
...
}
?>

please take in consideration the fact that you will have big problems with downloading (getting) hole files. In other words ‘temp.tmp’ file always will have the same size equal to first downloaded file despite the real size of downloading file. I have not idea what is the reason!

If someone will think that problem is just in getting proper file size (which you will get using filssize() function) he will be mistaken. The download file’s size is not equal to source file’s size materially, that means fflush() function will not solve the problem (I have tried this as well).

Finally the solution was founded: before downloading a file you will need to delete local file if such exist (‘temp.tmp’). So working code will look like:

<?php
foreach ($files as $key=>$path) {
... 
  if (
file_exists('temp.tmp')) {
   
unlink('temp.tmp');
  }
 
$result ftp_get($ftpConnId'temp.tmp'$pathFTP_BINARY);
...
}
?>

Good luck in scripting :-)

Why there isn't an "ftp_get_contents" function, I don't know. It takes a little work to emulate one, but it's doable.
<?php
function ftp_get_contents($ftp_stream$remote_file$mode$resume_pos=null){
   
$pipes=stream_socket_pair(STREAM_PF_UNIXSTREAM_SOCK_STREAMSTREAM_IPPROTO_IP);
    if(
$pipes===false) return false;
    if(!
stream_set_blocking($pipes[1], 0)){
       
fclose($pipes[0]); fclose($pipes[1]);
        return 
false;
    }
   
$fail=false;
   
$data='';
    if(
is_null($resume_pos)){
       
$ret=ftp_nb_fget($ftp_stream$pipes[0], $remote_file$mode);
    } else {
       
$ret=ftp_nb_fget($ftp_stream$pipes[0], $remote_file$mode$resume_pos);
    }
    while(
$ret==FTP_MOREDATA){
        while(!
$fail && !feof($pipes[1])){
           
$r=fread($pipes[1], 8192);
            if(
$r==='') break;
            if(
$r===false){ $fail=true; break; }
           
$data.=$r;
        }
       
$ret=ftp_nb_continue($ftp_stream);
    }
    while(!
$fail && !feof($pipes[1])){
       
$r=fread($pipes[1], 8192);
        if(
$r==='') break;
        if(
$r===false){ $fail=true; break; }
       
$data.=$r;
    }
   
fclose($pipes[0]); fclose($pipes[1]);
    if(
$fail || $ret!=FTP_FINISHED) return false;
    return 
$data;
}
?>

Something similar would work to write a ftp_put_contents function, too.

Crud. The _nb_ only refers to reading from the ftp server, and the buffer in the socket pair is only about 364 bytes. So it doesn't work for files larger than that size.

Here's a quick function that figures out the correct mode to use based on a file's extension.

<?php
function get_ftp_mode($file)
{   
   
$path_parts pathinfo($file);
   
    if (!isset(
$path_parts['extension'])) return FTP_BINARY;
    switch (
strtolower($path_parts['extension'])) {
        case 
'am':case 'asp':case 'bat':case 'c':case 'cfm':case 'cgi':case 'conf':
        case 
'cpp':case 'css':case 'dhtml':case 'diz':case 'h':case 'hpp':case 'htm':
        case 
'html':case 'in':case 'inc':case 'js':case 'm4':case 'mak':case 'nfs':
        case 
'nsi':case 'pas':case 'patch':case 'php':case 'php3':case 'php4':case 'php5':
        case 
'phtml':case 'pl':case 'po':case 'py':case 'qmail':case 'sh':case 'shtml':
        case 
'sql':case 'tcl':case 'tpl':case 'txt':case 'vbs':case 'xml':case 'xrc':
            return 
FTP_ASCII;
    }
    return 
FTP_BINARY;
}

// sample usage
ftp_get($conn_id$local_file$server_fileget_ftp_mode($server_file));

A subtle issue with the ftp_get() function. The second param, string $local_file, is a file name on the SERVER running the php script. It is NOT a file on the client machine running the browser. I erroneously tried to use this ftp to download a file from my site to my local system. I entered the full path starting with the drive letter ("h:/...") on a system running WIN XP and kept getting a failure of unable to open (destination) file. Only after just putting in a file name with no pathing did I see where the file was written. It was in the directory on my site where the php script is located (hosting is managed shared LAMP server which supports multiple url's, GoDaddy hosting).

ftp_sync is a way to walk the directory structure on the server and copy every directory and file to the same location locally.

<?php
$ftp_server 
"ftp.example.com";
$conn_id ftp_connect ($ftp_server)
    or die(
"Couldn't connect to $ftp_server"); 
   
$login_result ftp_login($conn_id"user""pass");
if ((!
$conn_id) || (!$login_result))
    die(
"FTP Connection Failed");

ftp_sync ("DirectoryToCopy");    // Use "." if you are in the current directory

ftp_close($conn_id); 

// ftp_sync - Copy directory and file structure
function ftp_sync ($dir) {

    global 
$conn_id;

    if (
$dir != ".") {
        if (
ftp_chdir($conn_id$dir) == false) {
            echo (
"Change Dir Failed: $dir<BR>\r\n");
            return;
        }
        if (!(
is_dir($dir)))
           
mkdir($dir);
       
chdir ($dir);
    }

   
$contents ftp_nlist($conn_id".");
    foreach (
$contents as $file) {
   
        if (
$file == '.' || $file == '..')
            continue;
       
        if (@
ftp_chdir($conn_id$file)) {
           
ftp_chdir ($conn_id"..");
           
ftp_sync ($file);
        }
        else
           
ftp_get($conn_id$file$fileFTP_BINARY);
    }
       
   
ftp_chdir ($conn_id"..");
   
chdir ("..");

}
?>

I tried to ftp a 7mb file today off my webserver.

I copied this example directly and it told me.

Port command successful
"there was a problem"

I thought it was because of the size.
But I guessed it might be cause of my firewall.

So I made the ftp connection passive:

<?PHP
 
 
...
 
$login_result ftp_login($conn_id$ftp_user_name$ftp_user_pass);
 
ftp_pasv($conn_idtrue);

?>

Ran the script again & it worked fine.

Hope this helps someone

Remember to use the full server paths to the directories you are working on. Server paths are not the same as "ftp paths".

I was using the path displayed on my FTP client to download and upload files and I kept getting "Not found" or "Permission Denied" errors.

On Windows (and possibly *NIX) you will get "[function.ftp-get]: failed to open stream: No such file or directory in..." errors if the local_file path contains directory paths that do not already exist.

Even with write permissions ftp_get can create the file but it will NOT automatically create the parent directories as you might expect.

If you ran the example and see that it fail after 90sec (timeout).

Then try adding:
<?php
ftp_pasv
($ftp_conntrue);
?>

Don't want to use an intermediate file?  Use 'php://output' as the filename and then capture the output using output buffering.

ob_start();
$result = ftp_get($ftp, "php://output", $file, FTP_BINARY);
$data = ob_get_contents();
ob_end_clean();

Don't forget to check $result to make sure there wasn't an error.  After that, manipulate the $data variable however you want.

I'd suggest use ftp_fget() instead of ftp_get() since the latter only return TRUE or FALSE and there's no obvious way to get the cause of failure.

   Using ftp_fget,  you have to pass a file handle as local file, so you have to do fopen() first. By way of this, you can find 'Permission Denied' problem when call fopen(). If you use ftp_get(), there's no way to find this error cause.

   In my case, I run httpd using 'nobody' and I create ftp local folder using 'haha'. It tooks me long time to find the 'Permission Denied' problem at that time since  I use ftp_get() then.

I am using ftp_get function to download a file from the FTP server to my web server where my php script is running.
On the webserver, I want the file to be downloaded to a directory which has a structure as follows -> Data/Files/localfilename.exe

However, when I specify the above string in the $local_file_name parameter of ftp_get I get an error saying the file does not exist.

I am running a Windows Server and the php script is running from C:/xampp/htdocs/file.php

Is there any way where I can specify the path on the web server where the file is supposed to be downloaded ?

Note that PHP still defaults to FTP active mode by default, which is almost never used anymore since the creation of firewalls.   Don't forget to add a ftp_pasv($conn, true) after your ftp_login.
