~*~ FTP Server To Server Recursive Transfer ~*~


Hello, Well many of us might want to change server every now and then, but wot abt moving whole contents which u uploaded in ur old site?
I was recently busy in making such script..coz i felt the need few days for my own sites..lolz :P
the given code snippet helps u in copying ur data recursively, even if ur folder contains other folders or file..everything will be copied.

<?php 
//-------------------------------------------------------------
//copyright: www.yaaridosti.net
//author: ViCkSy
//email: admin[at]yaaridosti.net (No Spam)
//-------------------------------------------------------------

$ftp_server = "yaaridosti.net"; 
$conn_id = ftp_connect ($ftp_server) 
    or die("Couldn't connect to $ftp_server"); 
    
$login_result = ftp_login($conn_id, "username", "pass"); 
if ((!$conn_id) || (!$login_result)) 
    die("FTP Connection Failed"); 
ftp_pasv($conn_id,true);  //needed since you may be behind a firewall

// changing the initial path on remote ftp server to public_html
ftp_chdir($conn_id,"public_html"); 

// getting the name of folder to copy recursively
// u may use a "." if u want to copy the whole structure inside public_html as it is.
$src=$_GET['src'];

ftp_sync ($src);  

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, ".."); 
         } 
        else 
            ftp_get($conn_id, $file, $file, FTP_BINARY); 
    } 
        
    ftp_chdir ($conn_id, ".."); 
    chdir (".."); 

} 
?>

u may modify the parameters (server, username, password etc) according to ur needs and use it in following way:
suppose u want to copy a folder named "xyz" in public_html from remote server to a folder "abc" on ur local server then
1. copy this code snippet (ofcourse after modifying with ur own parameters) in file say copy.php into ur local "abc" folder
2. call the script like

copy.php?src=xyz

* There will be no output of the script, u just need to check ur ftp folders to make sure the data is being copied.

* Sometimes it may result in internal server error in some servers (if the data is too much or in some unexpected situations)

* Sometimes a partial quantity of data might be transferred and script may stop if ur max limit of execution is exceeded.

Enjoy
