Need help with ftp_ssl_connect()

[sKunKbad]

I've been trying to connect to a CentOS server with ftp_ssl_connect, and I just get errors, even though I can successfully connect with FileZilla using FTPeS. These are the errors:

 

Warning: ftp_login() [function.ftp-login]: SSL/TLS handshake failed in C:\xampp\htdocs\script-library\connectivity\connectivity.php on line 72

Warning: ftp_login() [function.ftp-login]: Proceed with negotiation. in C:\xampp\htdocs\script-library\connectivity\connectivity.php on line 72

 

The server has vsftpd for ftp. It is configured for SSL, and again it works with FileZilla FTP client, so I don't know why it doesn't work with my PHP. Other than the above error messages, I don't really know how to debug or get more info.

 

$ftp_server = '123.123.123.123';
$ftp_user_name = 'username';
$ftp_user_pass = 'xxxxxxxxx';
$file = 'test.txt';
$remote_file = 'test.txt';
$remote_directory = '/home/username';

$ftp_output = '';

// Test if connection is HTTP or HTTPS
if ( 
isset( $_POST['do_ftp'] )
&& $_POST['do_ftp'] == '1'
)
{
if(
	isset( $_SERVER['HTTPS'] ) 
	&& $_SERVER['HTTPS'] == 'on' 
	&& function_exists('ftp_ssl_connect')
)
{
	// Set up secure ftp connection
	$conn_id = @ftp_ssl_connect( $ftp_server );
}
else
{
	// Set up standard ftp connection
	$conn_id = @ftp_connect( $ftp_server );
}
}

// Check if connection was made
if( is_resource( $conn_id ) )
{
$ftp_output .= '<span class="good">FTP CONNECTION SUCCESSFUL</span><br />';

// Login with username and password
if( $login_result = ftp_login( $conn_id, $ftp_user_name, $ftp_user_pass ) )
{
	$ftp_output .= '<span class="good">FTP LOGIN SUCCESSFUL</span><br />';

	// Turn passive mode on
	ftp_pasv( $conn_id, TRUE );

	// CD to the appropriate directory
	ftp_chdir( $conn_id, $remote_directory );

	// Upload a file
	if ( ftp_put( $conn_id, $remote_file, $file, FTP_ASCII ) )
	{
		$ftp_output .= '<span class="good">FTP UPLOAD OF ' . $file . ' SUCCESSFUL</span><br />';
	} 
	else 
	{
		$ftp_output .= '<span class="bad">FTP UPLOAD OF ' . $file . ' FAILED</span><br />';
	}
}
else
{
	$ftp_output .= '<span class="bad">FTP LOGIN FAILED</span><br />';
}

// Close the FTP connection
ftp_close( $conn_id );
}
else if( isset( $conn_id ) )
{
$ftp_output .= '<span class="bad">FTP CONNECTION FAILED</span><br />';
}

 

Output from FTP:

FTP CONNECTION SUCCESSFUL

FTP LOGIN FAILED
