    // set up basic connection
    $ftp = ftp_connect($ftp_server);

    // login with username and password
    $login_result = ftp_login($ftp, $ftp_user_name, $ftp_user_pass);

    // check connection
    if ((!$ftp) || (!$login_result)) {
    die(    "FTP connection has failed !");
    }

    echo     "Current directory: " . ftp_pwd($ftp) . "\n";

    // try to change the directory to somedir
    if (ftp_chdir($ftp, "somedir")) {
    echo     "Current directory is now: " . ftp_pwd($ftp) . "\n";
    } else {
    echo     "Couldn't change directory\n";
    }

    Thanks to h3 at valleyfield dot net

    Same function with some minor changes and comments added

    FTP function checks if a directory exists

    <?php
    function ftp_is_dir( $dir ) {
    global     $ftpcon;
    // get current directory
    $original_directory = ftp_pwd( $ftpcon );
    // test if you can change directory to $dir
    // suppress errors in case $dir is not a file or not a directory
    if ( @ftp_chdir( $ftpcon, $dir ) ) {
    // If it is a directory, then change the directory back to the original directory
    ftp_chdir( $ftpcon, $original_directory );
    return     true;
    }
    else {
    return     false;
    }
    }
    ?>

    Works like the other functions in this page's notes, but this one doesn't make use of a global FTP connection, so it takes parameters like the other functions in the extension

    <?php
    function ftp_directory_exists($ftp, $dir)
    {
    // Get the current working directory
    $origin = ftp_pwd($ftp);

    // Attempt to change directory, suppress errors
    if (@ftp_chdir($ftp, $dir))
    {
    // If the directory exists, set back to origin
    ftp_chdir($ftp, $origin);
    return     true;
    }

    // Directory does not exist
    return false;
    }
    ?>
