I will not be able to reproduce this bug until something on the network goes nuts again.  

in my case, it was my cable modem configuration combined with an ISP network upgrade.  after persistently trying to get an internet connection again (and many calls to tech support), I did.  

All is well now with my connection so I can't test the Accepted data connection error, but I did test mkdir and it appears to be working.

//ftp mkdir test
function mk($conn_id) {
    echo "chdir\n";
    if (!ftp_chdir($conn_id, "/public_html/")) {
        echo "chdir failed\n";
        return;
    }
    echo "mkdir test\n";
    if (!ftp_mkdir($conn_id, "/public_html/test")) {
        echo "mkdir failed\n";
        return;
    }
    echo "chdir test\n";
    if (!ftp_chdir($conn_id, "/public_html/test")) {
        echo "chdir failed\n";
        return;
    }
}
// set up basic connection
$conn_id = ftp_connect($host);
// login with username and password
$login_result = ftp_login($conn_id, $uid, $pwd);
// check connection
if ((!$conn_id) || (!$login_result)) {
    echo "FTP connection has failed!\n";
    echo "Attempted to connect to $host for user $uid\n";
    exit;
} else {
    echo "Connected to $host, for user $uid\n";
}
ftp_pasv($conn_id, true);
mk($conn_id);
// close the FTP stream
ftp_close($conn_id);

Environment
------------
PHP Version 5.2.4-2ubuntu5.3
Apache 2.0

Application: zip files http upload, decompression on webserver, ftp directory creation and files ftp transfer to remote ftp server;
Situation: a zip file with 2 directories within, each containig one file;

Reproduce Code
--------------
if(!ftp_put($this->conn_id,$target,$tmp_file_name,$ftp_mode)){
....//set debug information
}

$ftp_mode is 2

Actual Result
-------------
The two files have been transfered correctly but the second operation gave this error:Warning: ftp_put() [function.ftp-put]: Accepted data connection

This bug is still encountered today and there's definitely a problem with ext/ftp 
on this point. 

Using this class for example works completely fine : 
http://www.spencernetwork.org/ftp/ftp-class.txt

I suspect that when a certain amount of transfered data is reached, over one or 
more STOR commands, the upload socket goes wrong.

This is caused by the bug I posted about yesterday:
