    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;
    }
    ?>
