// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// try to chmod $file to 644
if (ftp_chmod($conn_id, 0644, $file) !== false) 
{
echo "$file chmoded successfully to 644\n";
}
	else
{
echo "could not chmod $file\n";
}
// close the connection
ftp_close($conn_id);
?>

<?php
$ftp_server="195.201.10.8";
$ftp_user_name="xyz123";
$ftp_user_pass="xyz123";
$file = 'C:/datasoft/test/test.txt';
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// try to chmod $file to 644
if (ftp_chmod($conn_id, 0755, $file) !== false) 
{
echo "$file chmoded successfully to 755\n";
}
	else
{
