PHP ftp functions don't work but lftp command does when psa-firewal enabled.

PHP ftp functions don't work but lftp command does when psa-firewall enabled.

Outgoing FTP from a PHP script - executed from command line.
With PHP 5.3.3 and PHP 5.5.10 script hangs on ftp_nlist() eventually returning an empty string.
ftp_pasv() function always returns false.

lftp works OK (out of box, empy .lftp directory).

Disabled firewall using:
service psa-firewall stop
PHP Script then works OK.

Any ideas?
I could always script lftp, but wanted to keep everything in PHP.

PHP Script looks like this:


$conn_id = @ftp_connect($this->_params->get('the_ftpserver'));
if ($conn_id === FALSE) {
$this->writeLog('Error: Cannot connect to FTP source', true);
return false;
}

$login = @ftp_login($conn_id, $this->_params->get('the_username'), $this->_params->get('tthe_password'));
if ($login === FALSE) {
$this->writeLog('Error: Cannot login to FTP source', true);
return false;
}

$contents = ftp_nlist($conn_id, ".");
if (empty($contents)) {
if (!ftp_pasv($conn_id, true)) {
ftp_close($conn_id);
$this->writeLog("No contents, cannot set PASV.", true);
return false;
}
$contents = ftp_nlist($conn_id, ".");
if (empty($contents)) {
ftp_close($conn_id);
$this->writeLog("No contents.", true);
return false;
}
}

Does not explain why lftp works when PHP FTP does not, but that's not important.
