// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); 
// check connection
if ((!$conn_id) || (!$login_result))
{
die("FTP connection has failed !");
}
echo "Current directory: " . ftp_pwd($conn_id) . "\n";
// try to change the directory to somedir
if (ftp_chdir($conn_id, "somedir")) 
{
echo "Current directory is now: " . ftp_pwd($conn_id) . "\n";
}
	else
{ 
echo "Couldn't change directory\n";
}
// close the connection
ftp_close($conn_id);
?>

Explanation

If the directory is changed, it echo can change the current directory. If not changed, it echo couldn't change directory. By using ftp_chdir( ) function, we can able to change the directory.

Example 2

<?php
$ftp_server="192.168.0.2";
$ftp_user_name="abc123";
$ftp_user_pass="abc123";
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// change the current directory to test
if (!ftp_chdir($conn_id, 'test'))
{
echo "chdir not successful"; // /test
}
else
{
echo "chdir successful. Directory changed to :".ftp_pwd($conn_id); // /test
	}
ftp_close($conn_id);
?>

In the above program, the directory is changed by using ftp_chdir( ) function. If the directory is changed, it prints chdir not successful.
